Listen Technologies LA-140 manual Mounting Your LA-107, Correct

Mounting Your LA-107

Mount the antenna in a strategic location. Your antenna may be placed either indoors or outdoors. If mounted outside, the highest elevation should not exceed 100 feet (30.5 m). The antenna should be placed in a location that will provide the best line of sight to the receivers. Keep in mind that the higher you have the LA-107 mounted, the more range you will get out of your receivers.

CORRECT

The LA-107 includes a bracket that allows it to be mast mounted (vertical pole) up to 1.5 inches (4 cm) in diameter. This pole can be made of metal or plastic. However, if using a metal mast, the LA-107 should be isolated from the ground. It is very important that your mast does not extend above the antenna radiator. This will create interference and multi-path to the receiver.

Mount LA-107 away from power lines, telephone lines and metal surfaces.

For maximum range, your transmitter should be set to “High” RF power.

Run the coaxial cable from the antenna to your device, keeping the cable length as short as possible (see page 4, Shortening the Coaxial Cable if necessary). To optimize the efficiency of the LA-107, or to extend the length of your cable run, RG-8 can be used in place of RG-58.
