TX4800 series IP67 VHF/UHF Commercial Radio
A truly remarkable product, the ingress protected TX4800V (148 Mhz – 174 Mhz) and TX4800U (450 Mhz – 520 Mhz) enjoy an enviable pedigree; GME’s thirty years of experience in marine radio.
The TX4800 series stands as unique in being the only waterproof 25-watt commercial mobile radio manufactured in Australia.
Compact in size, powerful, robust and reliable, the TX4800 series provides the perfect communications solution for use in the harshest of our Australian environments. The IP67 rating makes the series ideal for a broad range of market applications.

The TX4800 series offers outstanding feature sets, which make it an ideal choice for both broad band switching and multiple channel infrastructures. With 500 RF channels programmable and reusable in 50 Zones or groups the TX4800 series offers a truly generic dimension for wide area coverage. The large backlit LCD screen and 9 digit alpha tag feature allows for instant recognition of the operational channel and zone.
Equipped with a Flash Upgradeable 16 Bit microprocessor, the TX4800 series is the smart choice for both today and all future demands.
The new TX4800 series is also small with an overall chassis depth of only 70 mm, making it one of the smallest 25-Watt UHF/VHF Commercial Radios available. Purpose built rear cooling fins means the TX4800 series will deliver a generous transmit duty cycle assuring the user of a solid communications link every time.
Like other GME Commercial Radios, the TX4800 series is designed and built in Australia with feature sets that make it the right choice when communications cannot be compromised.
