Antennas
Antennas are purchased separately and include installation
instructions. Numerous type of antennas are available that range from
emphasis on easy of installation to emphasis on performance. Often
the difference in performance between many of the antenna is
modest.
1. Vertical Ground Plane Antennas:
These are omni-directional antennas that provide optimum
performance for contacting other fixed stations using vertical type
antenna in addition to all mobile stations. For medium to long
range communications work.
2. Directional Beam Antennas:
Highly efficient and directional antennas generally intended for
fixed-to-fixed very long-range communications.
Remote Speaker
The external speaker jack (EXT. SP.) on the rear panel is used for
remote receiver monitoring. The external speaker should have 8
ohms impedance and be able to handle at least 3 watts. When the
external speaker is plugged in, the internal speaker is disconnected.
Note: The PHONE jack on the front panel overrides both external
and internal speakers. When the plug from a headphone is plugged
to the PHONE jack, both internal and external speakers are silenced
simultaneously.

Public address
An external 8 ohms, 3-Watt speaker must be connected to the PA
jack located on the rear panel when the transceiver is used as a public
address system. The speaker should be directed away from the
microphone to prevent acoustic feedback. Physical separation or
isolation of the microphone and speaker is important when operating
the PA at high output levels.
