NOTE: Any two metal pieces rubbing against each other (such as seat springs, shift levers, trunk

and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause severe receiver

interference.

Fig 1 Multiple Antennas Separation for locations 1-10

Fig. 1 indicates the separation distances required for the various antennas used with XTL/APX

mobile antennas used with the DVR antenna. Each "cross-hair" symbol represents a possible

location (i.e. LOC) of an antenna. The recommendation is to locate them as close to the center of

the roof and/or trunk as possible, without interference with a lightbar. This picture is not drawn to

scale. For letters A, B, C, and D, Table A indicates the EXACT distance for separation of the LMR

antennas. For letters E, F, G, and H, Table B indicates the maximum distance between the edge

of the ground plane and the accessory antenna location.

NOTE:

• A minimum of 18 inch (46cm) separation is required between lightbar and any roof

mounted antennas, to prevent interference with the lightbar circuitry (see lightbar

manufacturer’s installation information).
