TX3820VB UHF 25W remote mount commercial radio

VHF 136 - 174 MHz NB remote mount 25 watt radio provides a powerful 25 watts of output power in a very small package.
Like the local mount configuration the TX3820VB has many calling options including CTCSS, DCS, MDC1200, MDC1200
and multi-tone selective calling which makes it an ideal network radio. It also incorporates the same rugged die-cast aluminium chassis
which allows it to withstand constant vibration and extreme temperatures.

The TX3820VB remote mount radio allows the end user to purchase a base radio and then choose between a
'Remote Head' or 'Remote LCD Microphone'. There are a variety of microphone options that can be used with the remote head
and as a part of the continued evolution of GME's under dash series it represents a major advance in commercia
l radio with outstanding features, performance and flexibility.

The TX3820VB offers the option of adding the RH004 remote head and the choice of the MC553BC standard microphone
or the new MC560BC IP67 microphone or even the MC540BC DTMF microphone to enable PSTN interface.
The TX3620UB also offers the MC522BC remote LCD microphone making installation simple.

With the radio measuring just 140 mm (W) x 195 mm (L) x 30 mm (H) mm the TX3620VB easily fits into the confines of modern vehicles.
The radio can be installed under the seat with the remote head or LCD mic option to be fitted to the centre console or dash.
The MC522BC offers the ultimate in radio looks and installation with all the features of using the TX3820U under dash series in the palm of the hand.
