Cellphone-Mate SureCall 80dB 2 Antenna Building System
Product Description
This dual-band 80dB (800/1900) system uses Cellphone-Mates' largest dual- band building amplifier. The complete system has been designed to broadcast an improved cell signal into multiple locations in large homes and small office buildings. Broadcast distance varies depending upon outside cell signal strength and frequency. Interior and exterior antennas should be separated a minimum 70+ feet to avoid oscillation between antennas. Interior antennas should be separated a minimum of 70+ feet. This system requires installation.
Special Note: This is a very powerful cell signal repeater. This type of equipment should only be installed by someone with experience with cellular amplifiers or under the direction of someone with experience and product knowlege with this equipment. Contact Powerful Signal and we will design your cellular system to give you the optimal performance.

Installation
Outside antenna needs to be mounted on the roof of your building. Outside antennas are designed to be mounted on a pole (max 2" diameter) using U-bolts. Coax needs to be run from the outside antenna to the amplifier. The amplifier can easily be mounted on a wall in an equipment, utility, or storage room. The inside antennas need to be mounted on a ceiling (dome) or wall (panel). Coax needs to be run from the inside antennas to the 2-way splitter connected to the amplifier. Standard wall plug power is required near the amplifier. Antennas do not require power.

Coverage Area
Inside coverage distance varies depending upon outside signal strength, carrier frequency (800 or 1900Mhz) and interior obstacles. The CM2020-80 has been designed to provide approximately 7,000 to 10,000 sf of coverage in low signal areas (1 bar outside) and up to 100,000 sf in strong signal areas (4-5 bars outside) with additional interior antennas. Note: These calculations are for 1900Mhz. 800MHz will provide more coverage. Please consult with Powerful Signal to determine expected coverage area for your situation.
Multiple antennas can be used with the CM2020-80 to enhance coverage within buildings. When multiple antennas are used, the system should be deisgned by someone experienced with the equipment. Powerful Signal will design your system for optimal performance in your environment.
Antenna Separation
Exterior and interior antennas need to have the proper separation. This is usually about 70+ feet depending upon several variables. Interior antennas should be separated 70+ feet.
-
Obstacles (metal, concrete, etc.) between antennas
-
Difference in height between antennas. Vertical separation is very effective.
Contact Powerful Signal for more information regarding antenna separation. We will help you design your system properly.

CM2020-80 Amplifier
The CM2020-80 is Cellphone-Mates largest dual-band (800/1900MHz) cell signal repeater for buildings. This amplifier has 31dB of adjustment for both 800MHz and 1900MHz along with 31dB of adjustment for both uplink and downlink. This adjustability enables the amplifier to be easily be configured in many different building scenarios.

Exterior Antennas
A choice of two different exterior commercial grade antennas are offered.
-
5dB gain Omni fiberglass
-
11dB gain directional
The omni antenna collects signal from 360 degrees, all directions. This antenna is generally recommended, and it works well in most situations.
The directional must be pointed in the direction of the cell tower(s). This antenna works best when there is a good line-of-site to the cell tower or the terrain is mainly flat or low rolling hills. Not recommended in low spots or dense forested areas.
Both antennas work with 800/1900MHz carriers. Mounting hardware is included and installation is required.
A J-Pipe Universal Antenna Mount is included with the system. This mount allows the exterior antenna to be easily mounted to a wall or rooftop.

Interior Antennas
A choice of two different interior antennas is also offered:
The dome is recommended in most situations when an attic or dropped ceiling is available. A panel is recommended in homes with vaulted ceilings and situations where antennas cannot be mounted on the ceiling.

2-Way Splitter and Jumper
A 2-Way splitter is provided. It is connected to the amplifier with a 2' jumper. The 2 output ports of the splitter are used to connect to each interior antenna.

Coax - 4 Lengths
This system provides four lengths of 400 low loss coax. A 2' jumper is is used from the amplifier to a 2-way splitter. Two equal lengths of coax run from the two ports on the two way splitter to each interior antenna. The length is used from the amplifier to the exterior antenna. Select lengths that best fit your installation environment. Remember: each foot of coax is signal loss so don't just get the longest length unless you need it. Figure what you need and select the length that best fits. Note: Never coil excess coax. It will cause problems.
