ANTENNA INSTALLATION
It is essential to select a good quality, high efficiency, VHF Marine antenna. A poor quality
antenna or one not designed for the specific frequency band you are using will give very poor
performance.
GME have a large range of suitable VHF Marine antennas to suit most installations and
applications. We recommend you contact your local dealer for advice, or visit gme.net.au.
Your GX750 is fitted with an ‘FME’ antenna socket. An ‘FME’ to ‘SO239’ adaptor is also
included (AD513).
If your VHF antenna cable is fitted with an ‘FME‘ connector you may connect it directly to the
‘FME’ socket on the radio. Simply screw the ‘FME’ connector onto the radio’s ‘FME’ socket and
tighten the nut using a small spanner or pliers.
Alternatively, if your antenna cable is fitted with a standard PL259 connector, you will need
to use the ‘FME’ adaptor to connect the antenna to the radio. Simply screw the adaptor onto
the antenna socket on the rear of the radio and tighten. Attach the ‘PL259’ connector to the
adaptor.
NOTE:
The antenna connector is not waterproof.
Extension speaker
If required, an extension speaker (SPK45 or similar) may be installed to improve sound levels in
noisy environments or in locations further away from the steering or driving position.
