just moved my CB aerial from a gutter mount to a body mount but cant get the SWR out of the red :(

i have good eirth as i can turn the radio on when the aerial is connected but without the negative power connection.

i have tried to remove the roof bars to see if this makes a difference but no joy, the Gutter mount us to have a 1.2 SWR

any advice (i have searched but all i find dosnt appear to help)

I had that, something about different potential between two earths, take the live n neg directly from the battery and try again ;)
 
OK, a few things here to try.

First off, take the aerial itself off and start measuring the cabling. Check outside of the connector to inner - should be infinite ohms. Check end-to-end on the inner conductor - should read very low ohms (at worst 1 or 2 ).

Has this antenna ever been used on a radio? Is it for the right band? Reason i ask is I've seen screwed-up packaging before that had the wrong antenna... :)

I suspect the cabling itself has a problem - internal short or something - and that is where I'dbe loooking.

Did you get it from Rocket Radio in Letchworth? They're generally quite helpful in there, even if you pop in with a query...
 
See if you can run a separate Earth from the mount to a six but of steel somewhere on the chassis/body.

Mine was like that but another earth got my swr down to less than 1
 
all sorted now :) was a small thred of wire linking both poles at the antenna mount end. SWR 1 to 1.5 now :)

So you had a short:p

Nice to see some CB guys here though I was never into CB. I am a licensed Amateur Radio Operator and will be installing an VHF rig for the local and neighbouring islands repeater and a multiband HF rig too.

I think I can get into the 11meter band and catch you guys from here :D

Is CB still popular there?
 
HAMs added via PM, Andy let me know if we can add you too.

OP we can add the CB guys too, let me know handle please.

Cheers.
