The Offroad Adventure Pack pairs the new and improved DTX4200X Dual Receive UHF CB Radio with the ANU230 6.5dBi ground independent UHF CB Antenna with elevated feed| heavy duty barrel spring base and fibreglass whip. The DTX4200X uses Oricom’s unique DUAL RECEIVE feature. It’s just like having two radios in one. This allows you to receive and listen to two different channels simultaneously. So if you’re talking to your mates on channel 64 and you are monitoring the highway channel on 40 you will be able to receive both transmissions at the same time| so you don’t miss an important conversation.
