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.
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.
