I have this one along with this Nagoya, and both have given identical performance off my Anytone 778UV and any handheld I've attached them to. I currently have the Nagoya on my truck as a permanent fixture and was using the other mag-mount as a bit of a field antenna, but have since decided to go a different route for a field setup and have that one as a spare. If you're interested I can give you the spare, just cover postage, I'm out of Seattle for reference. I'll understand if the Amazon link ends up being cheaper, but the offer is there.
