BRAND NEW UNIVERSAL ANTENNA ADAPTER (WATER PROOF) SUIT UNIDEN UHF RADIO UH076 UH078 MODEL P/N SMA-UHFWP NOTE RADIOS IN IMAGES ARE NOT INCLUDED IN THIS LISTING. We get many enquiries if there is a way of improving a handheld UHF radio's performance to something similar to a vehicle mounted system.This goes a long way toward helping this problem.By removing the radios small screw on antenna, this adapter screws on in place of it, and from there any UHF antenna system ( not supplied but see our other listings ) can be connected. This adapter matches the standard end of a UHF antenna cable and screws straight on. Ideal in an in vehicle situation where you permanently fit the antenna system to outside of the vehicle therefore not "insulating "the radio inside the vehicle, the signal can be received and transmitted from the outside, also good in caravans too. When you want the portability of the handheld radio back again just unscrew the adapter from the radio and screw the original radio back on .
