Tram 3500 magnet mount mobile CB radio antenna rated at 3500 watts, it has a 17' RG8X double shield coax with the PL259 connector, there is a rubber boot on the bottom of the mount to prevent scratching your vehicle finish, it has a 5" magnet base pre-tuned to mid-band CB frequency, easy set up for your SWR, I've used these antennas for years with excellent transmit and receive with amps used also, I've never had an issue with these antennas.
I took the antenna out of the original packing to test a couple of SWR meters before I had my base station operational only, then put it back in the original packaging, these are comparable to the wilson 1000 antenna, impressive reviews online to check out.
I am getting out of the CB radio hobby and selling all my remaining radio equipment
