FIG-1: RADIO CONTROLS & CONNECTORS
1
ANTENNA
The antenna radiates and receives radio
signals. Attach the antenna base to the BNC
connector on the rear of the radio.
NOTES: Position the antenna in vertical
position for best performance.
Use only the type of antenna
furnished with the radio, or an
optional Ritron antenna suitable
for the band you are using.
If the radio will be placed on a
horizontal surface, configure the
antenna hinge so the antenna
stands in a vertical position. If the
unit will be mounted on a vertical
surface with the Mounting Kit (see
Accessories, page 1), be sure the
antenna is in a vertical position.
