AlarmNet CELL-ANT3dBPK Remote Weatherproof Antenna Kit
Installation Guide

General

CELL-ANT3dB supports 14 global cellular frequency bands for 4G LTE, 3G WCDMA and CDMA. It should be used on
installations where the antenna must be mounted at some distance from the communicator.
CELL-ANT3dB is rated for outdoor installations but can also be mounted in attics, plenums and other indoor spaces. The
spoked ground plane reduces the effects of ice and rain on antenna performance while maintaining the antenna's low profile.

Signal Strength

For reliable service, the communication module should only be installed in locations where there is satisfactory signal strength.
The signal strength (green) LED lights steady to indicate satisfactory signal strength.
The signal strength value measured in dBm can be viewed on the 7720P Programming Tool, by using the shift <E> command.
dBm is displayed as a negative value on the 7720P. A value closer to 0 represents a stronger signal.
i.e., Signal strength of -60 dBm is stronger than that of -100 dBm.

Installation Guidelines

Use these guidelines you can maximize the performance of the communication module.
• Find the best coverage before final mounting by moving to several locations while monitoring the signal strength.
• The best signal strength can usually be found at the highest point in the building on an exterior wall. Avoid the basement.
• Do not mount the module on or near large metal objects such as steel I-beams, HVAC ducts, etc.
If consistent signal strength cannot be found with the internal antenna, an external antenna should be used.

External Antenna

The antenna is an exterior weatherproof antenna that can be mounted up to 50 feet away from the radio when the proper coax
cable is used. Refer to Table 1 for coax cable selection. Install the antenna as follows:
1. Measure and record the communication modules signal strength using the internal antenna for reference.
2. Disconnect all power from the unit including the battery.
3.
Remove plastic plug from the SMA mounting hole on top of the communication module housing and insert the SMA
end of the adapter cable. Secure the SMA connector with the included nut.

4. Plug the
port and route cable as shown.
5. Attach the antenna to the mounting bracket as shown in Figure 1.
6. Find a suitable location so that the antenna will be mounted vertically. The best antenna location is usually at the
highest point in the building.
• Avoid the basement.
• Avoid mounting on or near large metal objects.
7. Route the coax cable and make all required connections.
8. Restore power to the unit and check that the minimum signal strength (green) LED lights steady and compare the
new value to the value recorded in Step 1.
9. Adjust the location of the antenna if needed until the minimum signal strength LED lights steady green.
10. Permanently mount the antenna vertically using the hardware as shown. The included silicon rubber tape is used to
waterproof the antenna connection.
