Antenna information
The antenna (not supplied) is of critical importance, to maximize your
output power and receiver senstivity.
A poorly installed, inferior quality antenna or one not designed for the
correct frequency band will give poor performance. You should only
purchase an antenna designed for the 477MHz frequency band.
Antenna installation
1. Connect the antenna to the rear antenna socket using a PL259 coaxial
connector (not supplied).
2. To obtain maximum performance from the radio, select a high quality
antenna and mount it in a good location.
Never press the PTT or CALL
button before connecting the antenna to the radio.
Optional accessories
If required you may install an external (8 ohm, max 5w power) speaker
fitted with a 3.5mm plug (not supplied).
DC Power
The UHF088 is designed for 13.8V DC negative earth installations only.
1. Connect the negative (Black) DC power lead to the vehicle chassis or
directly to the vehicle battery negative terminal if preferred.
2. Connect the positive (Red) DC power lead via the in line fuse to
a suitable point in the vehicle fuse box or directly to the positive
battery terminal. When selecting a suitable point take into
consideration if you want your UHF088 to be operational when the
car ignition is off.
