I've got a couple of cbs from the 70's.
One worked espceially well until a repair shop replaced the meter with a
wrong one and stole the power transistor and put in a cheapie.
I have a new Ford and want a good or great cb and antenna that doesn't
require holes in the new pretty sheet metal.
I don't anticipate in rattling on the mike all day just keeping up on
road conditions wrecks etc.

I've tested a ton of antennas and the one I keep coming back to is a Hamstick made by Lakeview.

It's about 7' tall and I don't think he makes them for CB so I use a 10 meter and lengthen the whip until I see a flat SWR.

There's a lot of copies on the market but the real Lakeview Hamstick seems to be the best performer of all.

Only handles about 400w but out performs my Wilson 5000 with the 667 on it.

I use a 4-magnet mount and have no problems,
