No matter what kind of rubber duck antenna I use it is almost deaf. I connected it to my outdoor antenna and it works great. So I decided to try an antenna that came with my icom r-2 receiver. It is metal and extendable. It to woke it up also to receive like it should. It is frustrating that it doesn't work well with any rubber duck antenna . My Whistler TRX-1 and BCD 396xt handhelds do great with rubber duck antennas in the identical location and the same programming. .
