New fuel cell cabinet under Andrew brand offers environmentally
friendly power April 14, 2008 -The CommScope family of
integrated cabinets, for years one of the top choices by North American
telecommunications carriers, is being expanded under Andrew Wireless
Solutions with new products that address the unique requirements of
wireless operators around the world.
Andrew cabinets for wireless
operators are environmentally controlled enclosures that protect equipment
at a cell site or remote installation. Andrew's full line of integrated
cabinets connect and protect radio, power, amplifier and battery
electronics while delivering industry leading acoustic and thermal
performance.
The two newest additions to the
Andrew cabinet family, introduced this month, are the EcoPower™ Cabinet
and the RBA84 Series Cabinet.
EcoPower Integrated Fuel Cell Solution is
Eco-Friendly EcoPower provides an environmentally
friendly DC backup power solution for wireless and wireline networks, with
a cabinet design that is modular and flexible to meet the most stringent
backup power needs. The cabinet's proton exchange membrane (PEM) hydrogen
fuel cells, housed in a secure, weather resistant cabinet for outdoor
deployment, offers a smaller footprint and more dense power backup than
what has been available previously from competitors.
The EcoPower cabinet, at 63 inches
high by 45 inches wide by 52 inches deep, is the most compact integrated
fuel cell system available, providing up to 16kW in a single cabinet. With
power supplied by two 8kW fuel cells, the EcoPower cabinet is cooled
without use of outside air in a sealed compartment to keep out dust,
contaminants and condensation, thereby helping to prevent deterioration of
equipment housed inside.
With its cabinet cooling and
heating system, the PEM fuel cell delivers optimum power output at ambient
temperatures that can range from -40 degrees Celsius to 46 degrees C, with
an exceptionally high degree of reliability that helps ensure
uninterrupted power during utility power failures.
"Traditional battery backup
cabinets and diesel generators take a back seat to the capabilities of the
Andrew EcoPower cabinet," said Anil Trehan, chief technology officer,
Carrier. "This cabinet provides a superior eco-friendly power supply that
offers significant operational cost savings over the life of the cabinet.
It also is ideal at addressing mandated minimum power supply requirements,
such as the US Federal Communications Commission's recent ruling that
calls for at least eight hours of power backup at cell sites."
The Andrew EcoPower fuel cell
cabinet is currently available for field trials. General availability is
scheduled for June 2008.
RBA84 Cabinet - Flexible, Durable and Aesthetically Pleasing
Design The Andrew RBA84 Series Cabinet has been
designed specifically for the needs of wireless operators and original
equipment manufacturers (OEMs). Its flexible configuration enables it to
accept radio, power and battery equipment from various OEMs, providing
operators with long-term versatility at network cell sites.
The RBA84 Series also has
configurable cooling options, ranging from air conditioning to hydrophobic
or mesh filter air cooling, for optimal thermal performance, while
minimizing cost. It also utilizes variable speed fan technology to
minimize the acoustic signature. It is constructed of rugged 1/8th inch
thick aluminum, with UL50 and GR487 Zone 4 compliance, making it durable
for outdoor usage. Its aesthetic design includes a louvered front door and
three rear access panels, blending appearance and functionality.
"The RBA84 Series strengthens our
family of integrated cabinets for wireless applications," said Julie
Nielson, vice president, Product Management and Engineering, Andrew
Wireless Solutions. "Andrew cabinets are now more accommodating to various
OEM radio and power equipment, making them more versatile and available
for quicker deployment. Andrew cabinets overall help our customers protect
their considerable investment in equipment from environmental elements."

New enhanced stainless steel ground rods ensure that
current has a downward path to ground Harger
Lightning & Grounding recently introduced their new Stainless Steel
Enhanced Grounds Rods. The rods contain special salts that help lower soil
resistivity and are used in conjunction with ground enhancement material such as
Ultrafill. Ultrafill lowers the soil resistivity immediately around the
ground rod drastically improving its efficacy.
The New 300 Series Stainless Steel
EGR's are highly resistant to corrosion. They are also used to overcome
many of the problems caused by galvanic corrosion which can take place
between dissimilar metals buried in close proximity such as copper clad
ground grounds and guy anchors.
Some other applications for these
Stainless Steel EGR's are areas with acidic soils, airports, pipe lines,
power plants and other industrial sites. Harger has also designed the
conductor portion of the ground rod to help ensure the current has a
downward path to ground, where other chemical ground rod manufacturers
utilize a design which forces the electrical (lightning) current to go "up
hill".
Another unique feature Harger has
incorporated is an inspection cap on the top of the rod. This allows for
inspection of the electrolytic salts. Harger will provide additional salts
free of charge should the salts become depleted. Harger's Enhanced Ground
Rods are UL listed and are designed to last over 25 years. They are
available in a vertical or horizontal design.
Harger Lightning & Grounding
is a leading manufacturer of lightning protection and grounding equipment,
as well as exothermic welding materials for the communications and
electrical industries. Harger also provides design and engineering
services and specializes in offering total systems solutions for their
customers. For additional information, visit their website or contact them at:

DBI-SALA pioneers industry's first self retracting lifeline with tie-back
capabilities DBI-SALA, a Capital Safety brand, has
introduced the new Talon™ Tie-Back Self Retracting Lifeline that
eliminates the need for a separate anchorage connector, minimizing cost
and installation time.
This revolutionary fall protection device
offers a unique solution for providing a tie-back capability to the
recognizable self retracting lifeline. Complete with a unique hook with
5,000 pound gate strength, it is designed specifically for tie-back use
and increased durability.
Talon ™ is ideal for use in tower
climbing, maintenance and erection.
The single-leg and twin-leg 100
percent Tie-Back Talon ™ self retracting lifelines are designed to
withstand the forces that occur from tie-back use.
To gauge the
forces being exhorted on the fall protection device, the self retracting
lifeline is equipped with impact indicators on each leg of either the
single or twin leg versions.
"We are dedicated to the continuous innovation within the
construction industry," states Charley Bryant, product marketing manager
of hardgoods at Capital Safety. "We are eager to introduce this new
solution that offers a better, easier and ultimately safer alternative to
getting the job done."
Three layers of webbing in the tie-back area of the lifeline
provide more abrasion resistance for added safety. The 3.5 feet of
tie-back webbing ensures that the lifeline can be anchored around most
structures. |

Satellite positioning antenna alignment tool expected
to become a popular US carrier standard Although most European network operators have made the use of
SPAA05 tools as their standard, US carriers are energized by the
opportunity to finally have the ability to install their antennas with
exacting alignments that can be obtained within two minutes.
The SPAA05 range of GPS based antenna alignment tools
are specially designed to improve the nominal antenna azimuth of GSM, DCS
and UMTS Mobile cellular networks.
Two versions are available at this time. The standard
SPAA05 and the all new SPAA05-NEX. Both systems feature easy to use
antenna mounting and back-office software solutions.
The models measure, in real time,
the exact antenna bearing within two minutes after switching on the
system. When using the full software -100 count- an accuracy of 0.5
degrees RMS can be achieved.
Although a number of networks
operators have not specified their needs for such very high accuracy yet,
existing antennas on many sites show clearly that many installation
companies are not achieving the current requirements of ± 3° or ± 5° with
conventional methods like using a magnetic compass or other imprecise
methods.
Oftentimes setting the correct
antenna azimuth is a problem for many line and antenna crews who forget to
include magnetic declination or they do it backwards.
Tower steel and antennas interfere
with the operation of a magnetic compass, and carriers often find that
their coverage problems are effected by unacceptable, but unnoticeable
antenna alignment.
A simple five-step procedure on
site with the new alignment tools will measure and store the individual
antenna azimuth and other important site information. The file encryption
process secures the measurement results including time, date and position
stamping. Back-office processing takes only a few minutes per site.

Comsearch's AuctionPlanner will assist bidders in contentious 700
MHz FCC sale Bidders in the January 24, 2008 US Federal
Communications Commission auction of 700 MHz spectrum can arm themselves
with a valuable advantage-the new 700 MHz AuctionPlanner™
product from Comsearch, an Andrew Corporation
company.
It should prove to be helpful in
assisting bidders with an advantage in what may prove to be one of the
most controversial wireless auctions in history. This will be one of the
last chances for many years to get new spectrum, and many operators such
as Qualcomm, AT&T and Google will be obligated to bid on it whether
they have an immediate need for it or not.
AuctionPlanner provides the
critical information that spectrum bidders need to assess the incumbent
environment both prior to and after the January 24, 2008 auction of the
700 MHz frequency band, now used for television broadcasting.
AuctionPlanner enables users to easily identify current TV stations that
operate in the band, supported by customizable maps and spreadsheets that
detail existing coverage areas, operating parameters, station
classifications and ownership information. AuctionPlanner also helps
to provide estimates of the number of sites required to achieve FCC
wireless network build-out requirements.
"Reliable, complete information is
critical to be successful in the upcoming 700 MHz spectrum auction," said
Chris Hardy, vice president and general manager, Comsearch.
"AuctionPlanner is easy to use and
its wealth of data is organized specifically to benefit spectrum
bidders. With AuctionPlanner, customers can easily and quickly
assess the spectrum encumbrances and make sound strategic decisions on
their bidding process. In addition, the new 700 MHz licensees will
rely on the timely transition of analog and digital TV stations to their
final digital channel allotments. The clear picture offered by
AuctionPlanner of the current operating TV stations will help 700 MHz
bidders evaluate whether any incumbency issues remain in a market, and aid
in monitoring the successful transition of TV stations out of the signal
band after the auction." |

CAMI isolation systems
permit other antennas to be mounted on "hot" AM
towers
LBA Technology, Inc. announces the
CAMI series of new-concept broadband medium-power isolators for AM towers.
CAMI isolation systems permit other antennas to be mounted on "hot" AM
towers.
CAMI systems are specifically
targeted to isolate single auxiliary broadcast coaxial cables for STL's,
FM translators, low power FM, and television translators. Unlike commonly
used isocouplers, one CAMI fits all of these applications. They also have
the advantage of passing AC or DC current to tower top amplifiers, and are
more resistant to weather and lightning.
Typical CAMI system specifications
are:
* Broadband transmission
frequency: DC - 2000 MHz * Broadband impedance: 50 ohms, VSWR
<1.2/1 * Insertion loss: 1.2 dB @ 100 MHz, 2.6 dB @ 960
MHz * Broadband power capability: 2.0 kW @ 100 MHz, 250 watts
@ 960 MHz * DC power passing * AM isolation frequency range:
500 - 2500 kHz * AM working voltage: 10 kV
peak * Lightweight, fast installation
With pending FCC approval of
translators for AM daytime stations, CAMI will provide an simple, cost
effective, way to mount the translator antenna on existing AM towers
without major changes to the transmitting system.
LBA Technology President Jerry
Brown commented "The CAMI isolator brings simplicity and reliability to
the installation of other services on AM towers. The uninterrupted,
stable, low loss signal path for these services is a real advantage. The
rugged environmentally hardened construction will pay real dividends in
reduced ongoing maintenance costs."
The CAMI isolator is priced competitively with other,
less capable isolators, and units can be shipped
immediately.

Andrew Corporation to retire LDF5 and LDF7 coaxial
workhorse cables at year's end If you had been in the wireless
design or construction industry for even a short length of time, LDF5 and
LDF7 rolled off the tongue as easily as their corresponding coaxial cable
sizes, 7/8" and 1-5/8".
The low density foam
coaxial cable became so popular within Andrew Corporation's HELIAX ®
products group during the past 30 years that many newcomers as well as
industry veterans thought that HELIAX ® was the technical term for all
corrugated copper cables. In the mid 1980s, a government RFQ specified Andrew's
1-5/8" LDF7, but allowed bidders to provide an approved equal, "providing
that it is heliax cable and meets all of the electrical specifications of
heliax coaxial cable."
However, on December 31, 2007 the
popular LDF5 and LDF7 cables will have an Auld Lang Syne production run
and the coaxial cable workhorses will no longer be
manufactured.
Building upon the market success
of its two most significant recent cable product introductions, Andrew is
streamlining its long-running and market-leading HELIAX® product portfolio
and featuring alternative products that offer higher value for customers.
With the revisions to its cable
product offerings, equivalently sized HELIAX Andrew Virtual Air™ (AVA™)
and HELIAX AL aluminum series cables will serve as direct replacements for
the LDF5 and LDF7 series coaxial cables.
"While the LDF series cable has
been the clear number one choice in the wireless industry for more than
three decades, technology improvements over the past three years have
enabled Andrew to introduce a new platform for copper and aluminum cables
that performs better than LDF," said Mike Guerin, vice president, Antenna
and Cable Products, Andrew Corporation. "With the successes of our
new aluminum cable product and our AVA series copper cable, Andrew
customers now can choose from two types of cables that provide even
greater technological benefits than they enjoyed with LDF5 and
LDF7."
HELIAX AVA series cables are the
lowest attenuation copper coaxial cables in the industry. Compared
to Andrew LDF series cables, AVA offers better performance in radio
frequency applications, with up to 10 percent lower attenuation in a
lighter weight, easier to install cable. AVA cable is ideal for customers
seeking to increase cell site performance versus other cable choices,
Guerin explained.
HELIAX AL series aluminum cables
enable construction of wireless base stations with the standard electrical
performance of an LDF series cable, but in a lighter, more flexible
cable. AL series is designed for customers seeking a high
performing, lighter-weight cable with reduced installation
costs.
"Building off the long-standing
tradition of quality and excellence that Andrew has delivered to the
communications industry for decades with its HELIAX coaxial cable
products, the AVA and AL series cables are establishing new performance
standards for the latest generation of wireless networks," Guerin
said.
With the exception of LDF5 and
LDF7 series cables, all other cable sizes in the LDF family will remain in
production and available from Andrew.
Andrew is implementing a 4.3 percent average price
increase for HELIAX cable in response to market conditions, particularly
the continued increases and volatility in raw material costs. The new
pricing
will be
effective October 1.
Talley Communications Corp., a leading
distributor of wireless communications infrastructure and mobile products,
announced this week they have entered into an agreement with Andrew, which
allows Talley to continue
to distribute Andrew's
LDF products.
"We are extremely proud of our long term relationship
with Andrew and now welcome the opportunity to continue to offer these LDF
series of cables to our customers," said Mark
Talley, President of
Talley Communications.
"The ability to continue distribution of the LDF
series cable is extremely important to providing Talley's customers with
unequalled customer support and effectively maintaining long
term customer stability,"
Talley said. |

Lighter, more universal boom gate is introduced
The new Connect-It
Wireless Components' 13' boom gate is now a lighter more
universal version of the past gate, according to company President Jim
Schultz.
Schultz said the new universal foot set allows the boom gate to
attach to guyed or tapered towers with up to an 8" round leg or a 6" angle
leg. A larger foot set is also available for legs up to 12 ½" OD.
The face of the mount easily pivots to adjust antenna azimuths and
accepts up to five antennas. Schultz says one of the best features of the
frame is that the entire mount assembles in minutes.
The new boom gates are strong, designed with the tropical weather
of Florida in mind and are built to withstand winds up to 150MPH. They are
engineered to the latest industry standards (FL Building Code & TIA/
EIA- 222- G).
Engineering cut sheets are gladly supplied upon
request or just look on their web site
for the required engineering data.
The boom gate comes complete with universal foot set, 3' standoff,
face & support angles, 2 stiff arms, and 4 antenna masts. There are no
extra parts to purchase.
Connect-It Wireless' stringent designs have proven to withstand
hurricane force winds throughout the country. They have withstood five
Category 1, five Category 2, four Category 3, and one Category 4
hurricanes without a single reported failure, Schultz says.
"We have achieved this success rate with an engineering philosophy
that accounts for a nearly infinite mount and antenna configuration," said
Schultz.
The veteran manufacturer explained that their published load limits
are conservative and generic in nature.
"These limits allow virtually any shaped antenna to be mounted at
any altitude and at any azimuth. To accomplish this goal safely, we assume
worst-case conditions in our analyses:
1. The antenna weight will equal the Maximum Combined Load
Weight; 2. The antenna wind drag will equal the Maximum Combined Load
Force; 3. The antenna area will equal the Maximum Combined Load
Area; 4. The antenna area will be the largest cross-sectional area of
the antenna; 5. The mount's effective projected area is the largest
cross-sectional area of the mount; 6. The mount's effective projected area
normal to the azimuth is the cross-sectional area of the mount normal to
the largest cross-section area of the mount."
EPAT and EPAN to assist
engineers
"Our load ratings are determined in accordance with
TIA-EIA-222-G, the Florida Building Code 2004, and A.S.C.E. 7-02. Revision G of
the TIA-EIA-222 code was substantial and we are in the process of updated
our drawing database so that all of our drawings will provide the
mount's total effective projected area (EPAT) and the mount's effective
projected area normal to the azimuth (EPAN). We will also provide load limits
at two wind speeds, 140 MPH and 150 MPH," Schultz said.
"Of course, we can increase these limits for site-specific installations," he
explained.
"To simplify access
to this information we plan to provide the same information for
each mount on our web
page in the coming months. We believe this will make the engineer's
life a little easier to spec mounts for their specific needs," he
said.
Ex-Press™ coax mounting band allows
for easy installs on
poles
Andrew's new Ex-Press™
Expansion/Compression Coax Mounting Band has been one of the industry's
most sought after products for installing multiple runs of coaxial cable
on the inside or outside of round or polygon structures up to 60" in
diameter.
Their Ex-Press™ Band is
the only coax mounting band in the industry featuring both expansion and
compression capabilities. The Express™ Band can be mounted on the
inside of water tank access tubes with 36" to 60" inside diameters or the
outside of round and polygon monopoles with 10" to 60" outside
diameters.
Long noted for their
innovative field-tested products, Andrew's mounting bands are
available from: Primus Electronics , Talley Communications and TESSCO.
Safety
and structural integrity highlight two monopole
products from B&C Two new monopole-related products were
introduced to the industry by B&C Contracting at the 2006 PCIA show in
Nashville, drawing interest from contractors and carriers
alike.
To help protect the monopole owners' assets,
B&C has developed their POLE-CAM©, designed exclusively for viewing
and recording the inside of monopoles.
The system enables contractors to determine the
location of all coaxial lines as well as combustible materials such as
bird nests that can be ignited when contractors are welding upon the
structures.
"Although it is important to have a fire
prevention safety plan in place whenever you are welding on a monopole,
that's a reactive measure," said Doug Coberley, President of B&C
Contracting.
"The POLE-CAM© system can prevent fires by
clearly identifying where there are areas within the monopole that should
be addressed whenever you are going to weld on the pole," he
said.
Coberley points out that the system is an
excellent tool for ensuring the safety of transmission lines and other
assets for any tower modification whether it is a welded, bolted or a
porthole installation.
Numerous fires are reported every year within
monopoles. In most instances the highly flammable transmission lines will
cause severe damage to the pole causing expensive replacement costs and
carrier interruptions.
"POLE-CAM©" comes equipped with a 2"
diameter wide angle lens with 24
LED lights built into the camera lens. It has 500'
of coax cable and a monitor with integrated DVD as
well as a DVD Recorder.
The
"POLE-CAM©" system is self contained in a roll-around enclosure. To
identify how easily the inside of the pole can be investigated, a
video is available at www.bandccontracting.com
Porthole rim easily provides
compliant entry for new tenants
In order to provide a complete joint penetration weld, contractors must use a backing material or
weld from both sides of the monopole.
When installing portholes on the top of most monopoles it is impossible to weld
on the inside. Coberley said his entry port allows for a CJP at
any level from the outside of the structure.
"Although you can weld on the inside of a
bottom port in most instances, this product will not require a confined
space entry permit and all the safety requirements that are necessary," he
said.
