Hello all! I'm looking for a replacement antenna for my Yaesu VX-170 (current version is the FT-270R) handheld HAM radio. Need something to help boost output without killing the battery. A lot of folks "out there" have suggested replacing the rubber duck antenna. I have an SMA to BNC adaptor (I also use this as a mobile and the adapter allows me to plug into my truck's antenna). Any suggestions?
