1.Select a location that is free from spray and splash.

2.Keep the battery leads as short as pos- sible. Connection directly to the

battery is most desirable. If direct connection cannot be made with the

supplied r power lead, any extension should be made with # 10 A WG wire.

Long extensions should use larger wire.

substantial loss of performance for both receiving and transmitting.

4.Locate your antenna as high as possi- ble and clear from metal objects. The reliable range of coverage is a direct function of antenna height.
