Please note.  The CM65W Dual Band 65dB Office Window System should only be used if no outside exterior cellular
antenna can be mounted.  It is always preferable to have an exterior antenna on the roof if at all possible.  See our
CM65 Dual
Band 65 dB System if a rooftop antenna is an option.  If rooftop antennas are not an option then the CM65W system should be
used for medium office spaces of 1,000 to 10,000 sf.  This system is ideal for high-rise office space with window access
facing the cell towers.  

If you have any questions, please contact us at Powerful Signal and we will help answer your questions.  We have experience
and knowledge in large office and warehouse cellular systems.

Powerful Signal's CM65W Dual-Band 65dB Office Window
System, powered by Cellphone-Mate CM2020 dual-band
amplifier, is a complete system that includes amplifier,
coax, antennas and power supplies.  Powerful Signal has
designed the CM65W to handle a weak cell signal
problems in high-rise buildings that do not have the option
of a roof-mount exterior antenna.

Each frequency, 800MHz or 1900MHz, can be manually
adjusted for coverage balance.  The CM65W will
simultaneously provide coverage for Verizon, ATT, Sprint
and T-Mobile as well as any 800/1900 MHz
GSM/CDMA/TDMA carrier (except Nextel/iDEN).  This easily
installed system can be implemented in a short amount of
time with little or no experience required.  Powerful Signal
provides technical support from product selection all the
way through product installation.

Product Description
65dB (800/1900MHz) system using Cellphone-Mate
CM2020 adjustable dual band (800/1900) amplifier.  

There are 5 components in this system:
65dB dual band (800/1900) amplifier
Inside Dome Antenna
Window Panel Antenna
400 Coax from amplifier to Inside Dome
240 White Coax from amplifier to Window Antenna

The amplifier can also be laid flat on the tiles in the dropped ceiling or mount on a nearby wall.  The window-mount
panel antenna needs to be mounted on the inside of the
window that faces towards your cell towers.  If your cell
towers are to the north, mounting the window panel on the
south window will not work.  20' of white LMR240 is
provided to run from the window-panel up into the dropped
ceiling where the amplifier is located.

The inside dome antenna needs to be mounted on the
ceiling.  Coax needs to be run from the dome to the
amplifier.  Standard wall plug is required near the amplifier.  
Antennas do not require power.

Mounting and installation is required with this system.  
Window panel needs to be mounted on a window that has
usable cell signal (make and hold a call).  Interior dome
antenna(s) need to be mounted on the ceiling.  Coax cable
needs to be run between antennas and amplifier.

Coverage Area
Inside coverage distance varies depending upon outside
signal strength, carrier frequency and interior obstacles.
The CM65W system has been designed to provide
approximately 1,000 to 1,500 sf of coverage in poor signal
areas (1-2 bars outside) and up to 10,000 sf in strong
signal areas (4-5 bars outside).  Please consult with
Powerful Signal to determine expected coverage area for
your situation.

In-building design assistance is available from Powerful
Signal.  We will work with you on your small or large cell
signal problem.  We have the experience and the product
knowledge to help you solve your problem.

Antenna Separation
Window-mount panel antenna and inside dome antenna
need to be
separated approximately 40-60 feet depending
upon conditions.  Contact Powerful Signal if you have any
questions in this area.  Our building experts will be glad to
assist you.
