Hi guy's and gals(didi) ;)
I'm off playing in a disused quarry on the weekend (sunday) So I decided to get myself a swr meter for the cb cos it's never been great to be honest :roll: Turns out that with the gutter mount i cant get the reading out of the red on rev,And with the mag mount it's only just coming out of the red. Seem's bad earth plane is to blame :evil: What's the best way you guys have found to solve this ? I've tried on the bonnet, sunroof and gutterings with no change in readings ? Any idea's ?
-
Possibly an faulty earth on the patch leads ??/
If you've tried two antennae, that would be my next thing to look at ..........
-
What's a patch lead ??? Is that the lead from the ant to the swr to the cb ?
-
check the conections are okay on the ariel end and the cb end
-
run a good earth to the aerial mounting. & try again. If that works you will need to scratch the paint off the gutter so you are getting a good earth...or run a permanent earth to it ;)

TBH if the ariel cables are made up properly then the earth plane shouldn't be a problem, mine isn't. I know the ally roof doesn't help but there is enough steel in the frame to make a good earth.
I have my guttter mount above the rear door and I managed to get a SWR above 2 (or is that below, better than anyway) though when I check it now I don't get a reading, I think the SWR meter has hit the dashboard one too many times now.
