Alright, so I have a Retevis RA25 mounted in my Xterra. Right now I'm using an NMO mag mount MXT-A26 antenna. It works great for GMRS. I used to have the Nagoya UT-72G mag mount hooked up to a TD-H3. I seemed to be able to get a lot more reception on that set up, using both GMRS and HAM. With the UT-72G, I was able to get NOAA channel 5 in super clear, plus I think channels 4,3, and 1 a little bit. With the MXT-A26, I can only get NOAA channel 5, from the same spot.
I know the MXT-A26 is tuned specifically for GMRS. My question is, should I get the Comet 2x4SRNMO antenna? I would like to be able to just screw it into the NMO mount and not switch out the whole thing. I'm not HAM licensed yet, but I like to listen. And also I would like to have it in case of emergency. Plus I probably will eventually get my HAM license.
