CB standing wave adjustment

[Dieselpwrdredneck]

OK you CB gurus.
Just put my K40 Trucker antenna on with a K40 57 inch whip with a cobra 29 and i cant seem to get my standing wave down? It is right around 3. I had the same radio in my old truck with a K40 Mag. mount and the standing wave was perfect, 1.

Any ideas?

Try changing the location of your antenna.

is the antenna grounded well ???

Many times it makes a difference on where it's located that determines the swr level.

Are you using the coax kit that came with the antenna? If yes tell me the length and the type(it'll be printed on the coax)

I generally recommend RG-8X coax to everyone using CB's for it attenuates the least,is flexible as the house RG-58 coax and does SWR's very good.

If he went from a mag mount on the roof to a whip mounted behind the cab or on the bumper that might be the problem.

It could be interacting with the back of the cab or the tailgate. If so, relocating it might help.

How long is your coax? It should be 18 foot or 20 foot long.

Depending on the length and type coax it is you can loop the extra coax 6-8 times into a coil creating a choke which can improve both swr and performance although one goes in hand with the other.

I'll have to loook into a couple of these, i really dont want to move it, i kinda like it there, but we'll see

Yeah if aesthetics are more important performance I say let it be
