27 Mhz antenna. A poor quality antenna or one not socket. (see diagram below) designed for the specific frequency band you are using will give very poor performance. Since the gX300 is capable of being switched between Screwdriver the 27 Mhz Marine and the 27 Mhz Cb bands, it is important to connect an antenna suitable for the band you have selected. because each band is in a different locking lever part of the frequency spectrum it isn’t possible to have a move to left to single antenna that will work well on both bands. You will Cable release plug therefore need to select a suitable antenna to suit the band you have selected. gME have a huge range of suitable 27 Mhz Cb and Cable entry hole 27 Mhz Marine antennas to suit most installations and applications. We recommend you contact your local Dealer for advice. Connect the antenna cable to the rear antenna socket using a pl259 coaxial connector. If required, replacement microphones are available with plug and rubber boot already fitted. Note: The antenna connector is not waterproof. NOISe SUPPReSSION 27 Mhz Marine and Cb radio can be prone to electrical and ignition interference. The reason is that electrical noise is a form of AM transmission similar to that used by your radio and your radio’s receiver is very sensitive. In most cases, ignition noise can be greatly reduced or eliminated by selecting the Noise Limiter (NL) key on the radio. In some severe cases, additional suppression may need to be fitted to the ignition system of your vessel or vehicle, in which case we recommend you consult an auto or marine Electrician for advice specific to your installation. -
