2.Placing the BTR on top of a shelf or equipment rack un- obstructed without remoting the antennas is OK.

1.Placing BTRs in a shelf or equipment rack and using re- mote antennas is OK.

3.Placing BTRs in a shelf or equipment rack with the an- tennas mounted on the back of the BTR or the side of the rack is BAD.

Antenna Placement

Improving Reception and Increasing

Range

Keeping the distance from the base station and beltpack as short, and unobstructed as possible will produce the most reli- able performance.

The base station is supplied with two antennas. This should provide satisfactory system performance in most applications. System range can be enhanced by remoting the 1/2-wave an- tennas. The ½ wave antennas are ground plane independent, so a ground plane is not required for good performance.
