You would be better off getting the BTech AMP-U25 amplifier from Amazon. Easier to return if it doesn't work and it will have better customer service through BTech. And it will keep you at the legal 50 watt limit for GMRS.

I have one. Bottom right corner of photo.


The power output falls off outside of the Ham band. For example the DC current input at 13.8VDC with 4 watts of RF input was about 5 amps. At the GMRS frequencies it dropped to around 3 amps. I need to put it on my Bird watt meter and get a power measurement now that I got some higher power UHF slugs for it. I'm guessing I'm only getting MAYBE 20 to 30 watts at most out of it on GMRS frequencies.
