Hi all, I'm having some trouble as a new ham with my UV-5R. I purchased an Expertpower 7.5in whip antenna for my radio a few months back and it performs fine with being able to hear my local repeater (VHF) 5 miles away. I can't transmit reliably from my location, but that's not my current concern. I purchased a Tram 1185 for use on my car, and wanted to test it from my inside my home location. I have 2 UV-5Rs...one with the Expertpower antenna and the other with the Tram 1185 hooked up via an SMA to UHF cable. With the Expertpower, I can hear talk on the repeater just fine, but with the Tram I hear nothing at all. I also switched the antennas to make sure it wasn't my radio. Can anyone help me understand what might be going on? Thanks.
