The Window Clip Antenna is quick and easy to install in any style vehicle and may be taken to remote sites or used on car rentals. The STI-CO antenna this constructed with the flexi-whip mast that will bend but will not break. It is field tunable between 136 and 1000 MHz and small enough to fit inside a briefcase. When mounted on the side window of a car or truck the mast will extend above the car roof - thereby significantly improving the performance of a hand held radio compared to the standard "rubber duck" antenna. It works as well as a fender or trunk lip mount antenna with a mobile radio and will handle up to 150 watts.
