Important!
It is very important to make your power connection to a source that
only supplies 12V when the vehicle key is in the accessory or ignition
ON position. A connection to a 12V source that is always on,
regardless of the key position, can lead to a battery drain if the
CommanderMT System is left on when you leave your vehicle.

Where to locate
• Best reception is achieved with the antenna mounted on a flat
portion of a metal vehicle roof with at least 12” x 12” of surface area
and a minimum of 6” from a window or sunroof.
• If the vehicle has roof racks or skid ribs, it may be necessary to
mount the antenna off-center.
• If the venicle roof does not provide sufficient metal surface area,
then the antenna can be mounted on the metal trunk lid. It is
recommended that it be mounted at least several inches from the
rear window to ensure adequate clearance.
