It's a CB, 10 Meter HAM, but so much more. I just ordered 3 of them for our investigations team, anxious to receive and install. My only reason for wanting a door mount was to free up space, but I after reading about the flex, bounce, that you mention, I'm not sure if it's such a great idea. Center console area is a pain because I am constantly parking, jumping into the back seat, and anything that is in the way is usually painful or broken. I've got to mount a laptop, new CB(+), 2 phones, 3 external cameras, dash cam, handheld video camera, handheld camera with large lens, Ipad, and still manage power for all of it, and have room to move around.
There has to be another 80 user that has a setup like this and manages it.
