Installed on my 2022 Jeep Wrangler Unlimited with the new -575 GMRS radio. The radio came with a standard 6" antenna. I have not tuned either antenna but the MXTA26 seems to give me about 20-25% more range.
Changed from original antenna that came with unit to this antenna and am super pleased with the new “range” it now has, so, we purchased additional antenna’s for all of our units.
