The Ultimate 4×4 Touring Pack pairs the new and improved DTX4200X Dual Receive UHF CB Radio with the popular ANU1100 All Terrain Antenna. 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.
