What the heck is this?

For receive maybe...? But it sure ain't a kicker.

 

i think that is a mounting braket. made so you can easily remove it from the truck. Dose it have some sort of slide mech. on it?

 

It is a quick disconect slide mount so you can take you radio in and out of the truck you mount the top half on the roof and slide the bottom half along with you radio out of truck. Anti theft device, if it is not in the truck they can't steal it. You can also mount it on the bottom and use it on the dash board.

 

It probably is from the same era as the radio. The only malady that often afflicts them is that corrosion from exposure to the air can build up on the copper or phosphor-bronze connections that are made & broken each time the CB (or stereo or ham rig...) are installed or removed for being stashed. To a point, they're "self wiping", meaning the mechanical action of sliding the two halves together (or apart) lets the "active surfaces" on both halves of the mount kinda wear off the gunk and provide for clean metal-to-metal connections.
To do it right, however, I'd treat all the connecting surfaces once or twice a year with Caig® De-Oxit. It's pretty spendy in a little bottle, but they sell a 2 cc. tube for about $4 that'll will outlast the radio -- a little tiny bit goes a long way. Dab some on a Q-tip and use it to scour the copper-colored surfaces for a few seconds.
I use similar products from the same company (actually 4 different products) for maintenance of volume controls, hot tube pins & sockets, plated (usually gold) contacts in computer and ham equipment, and a conductive lube for conductive plastic controls ("Faders") on sound mixing boards. But good old De-Oxit (formerly called D5 and R5) are the same stuff. You can pay around $18 for a can of spray (kinda wasteful except for putting inside pots) or $25 for a "nail polish bottle", but it'll last forever. If you're not using it often on a professional service bench, I'd just get the 2 cc. tube and toss it in with the CB accessories, or hold it to the side of the radio with a glob of masking tape.

It's well worth the cost, as those antenna and audio contact tabs get gunked up pretty easily when they're not engaged.

That's most likely a better radio than some of the nice new ones out on the market.

 

I don't see any reason you could not use it on any radio. I used one of those back in the day when they first came out. I didn't use their electrical hookup, just used the stock Cobra power plug and plugged it in and out, I thought that worked better and unscrew your coax, took about 15 seconds and took the radio in to the motel.

 

Yep, quick disconnect for the radio........They had several problems tho..."Good idea", but usually they didn't slide together all that good for a good connection on the coax, which caused connection problems with the antenna...

Other major issue with them, was guys got to where it seemed like too much trouble to un-hook the radio and take it with them, or stick it in the trunk, if they were just running into a convenience store for a drink or pac of smokes, so they would leave the radio in place...Guess what? The slide-disconnect also makes it easier for thieves to steal the radio!

Some actually had Key switches, so you needed to use a key to unlock the sliding bracket before you could remove the radio...Which I always thought made the bracket pointless to begin with...
