Figure 2-2: Typical Antenna Mounting

CAUTION

DO NOT allow the pole or other surfaces to extend higher than the underside of the

antenna. Such a condition would impair signal reception.

The most important consideration in selecting a position for the

antenna is the presence of objects which obscure the sky or horizon.

Where possible, there should be no obstruction to a full view of the sky.

Overhead wires and other very narrow obstructions may be considered

as invisible to the signals, provided that they are a few meters away.

Large flat surfaces can decrease performance of the receiver.
