Ok thank you so much!! Below is my mobile set up for UHF/VHF/GMRS

Last week confirmed with DX Engineering that my Diamond X50 will work on GMRS - right now that bad boy is SWR 1 perfect we tested it on a rig expert and that device I was asking about - I just want to key up on my GMRS radios to be sure - hence the original question [key up on my mobile set up and my Diamond X50].
I'll check out your recs, always like to have a couple antennas - the Diamond X50 has survived tornadoes, ice storms and still working like a charm! My friend's comet works great !
I run HF, UHF, VHF, GMRS, and wanted to give CB a little try. I have a CB dipole to deploy and looking for something low key for mobile. Also taking a crack at CW via Long Island CW club. When we get these flood events, never hurts to have multiple modalities of communication. I find GMRS operators are so much fun and we have lots of repeaters popping up in Texas. I really have to thank Randy for his videos - that is what got me into GMRS.
Have a Blessed Sunday WRXP381
Best, LMC
