Currently I'm running a Comet SBB-2 dual band, but have it for sale on QRZ.com Got a Comet SS680SBNMO being delivered today. Both are between 18-21 inches tall.
Actually drilled another hole a little further back a few weeks ago. Decided to add another NMO mount to install a CB antenna. Seems to work way better than the Lil Wilson I was using. Have an antique CB right now but looking to get a Cobra 75.
