The selection of the antenna is critical to system performance. The selected antenna must be 

 

50 Ohm impedance and capable of at least 50 Watts. Gain antennas may be used to increase 
system coverage. Please take note of licensing restrictions when selecting gain antennas. Some 
services or regions may have antenna gain or system ERP limitations. 

The antenna must be connected to the duplexer with a high grade 50 Ohm transmission line 
(hardline). The line must have connectors to match the connectors on the duplexer and antenna. 

 

For proper antenna installation, please also consult the Motorola Quality Standards Fixed Network 
Equipment Installation Manual R56 (6881089E50).

It is important that all antenna cables are grounded at the point they enter the 
building.

The antenna design is the customer's responsibility. All aspects of the antenna 
design must comply with the relevant local regulations.
