A10-RX User Guide

Antennae 

The SMA antenna connector is used to mount the included 1/4-wave whip antenna  For specialty 

applications external, high-gain receiving antennae can be attached to the SMA connector  

 

ª

Ensure that the antennae used are built for the correct frequency.

For best operation and reception power with the included 1/4-wave antenna, keep it in the free 

field, away from direct contact with the wearer’s body. When multiple wireless systems are in 

use keep transmitters separated by at least 1/2-wave distance of the transmitted frequency.
