EXT. SP.

CAUTION

Avoid routing the cable next to sharp edges or moving parts, which might damage the cable.

Do not run the cable next to power cables or other radio antenna cables.

Do not run the cable through the engine compartment or other areas that produce extreme heat.

Ô NOTE Ô

Do not connect the black wire to a non-metallic (plastic) part, or to any part insulated from the vehicle’s chassis by a non-metallic part.

Dual band antennas provide optimum reception of CB and WX channels. For mobile installations (car, boat), a non- directional antenna provides the best CB reception. Mobile antennas use your vehicle’s metal body as a ground plane. If the CB is installed in a boat, your boat’s steel hull is used as a ground plane. Without a steel hull serving as a ground plane, you will not receive maximum efficiency. Before using your CB in a boat, consult with your boat dealer regarding an adequate grounding system.

Keep in mind that for the best performance you should mount the antenna:

as high as possible.

 

 

 

 

 

 

as far as possible from sources
