A trusted UHF radio, built for the harsh Australian climate

GME has recognised the need for a compact ingress protected UHF radio, resulting in the new TX4600 radio. The TX4600 is ideal for any environment and is especially suited for use on quad bikes or tractors. A striking feature of the TX4600 is the large tri-colour backlit display clearly indicating the selected channel, signal strength and many other selected features. The clearly illuminated push buttons include second functions. The microphone includes channel Up/Down keys and a Priority channel button making these features a simple one-handed operation. As with all GME mobile UHF radios, the TX4600 is designed and built in Australia and compliments the TX3100, TX3340, TX3500 Series and TX4500. The TX4600 can be flush mounted with or without the optional MK001B Flush Mount Kit.
