Important Things to Note Before Starting Your Installation

Coaxial Cable

If you plan to use your own coaxial cable instead of the provided cable, you must use cable and connectors rated at 50 ohms. Although cable used for cable TV installations looks similar to this cable, it won’t work with your Listen system.

If you need to run cable over a greater length than 50 feet for 216 MHz applications or greater than 100 feet for 72 MHz applications, we recommend that you use RG-8 cable rather than RG-58. It is a lower loss cable, meaning that more of your signal will reach the antenna.

Long cable runs can result in signal degradation due to “loss” characteristics of the cable. At 72 MHz, there is a loss of 2dB per 100 feet of cable and at 216 MHz, there is a loss of 5 dB per 100 feet of cable. (A 3dB loss means half of your power has been lost.) However, it is better to suffer coaxial power loss than to try to shoot your signal through obstacles! Obstacles, especially metal, can create drop-outs or reflections of your sig- nal that will result in poor listening conditions.
