Where's your aerial.
I'm not saying that this is the problem, but UHF is designed for line of sight.
If it's not too much trouble, you might want to try moving it. The higher it is, the better reception you should get.
My 2c worth.

on the bullbar normal spot rosco, i was thinking that, but why do others have no problem in the same mounting on the bullbar, it does extend slightly above the roof but not heaps.
Is it the same vehicle behind you that has trouble receiving you? It may be it's their CB playing up and not yours?
Mine sits on a magnetic base on the bull bar and I don't appear to be having any probs.
Have you checked the coax for kinks and breaks?

PS: 20m is waaaaayyyyyy too close to sit behind somebody, at speed!!!

rosco, not at speed mate just up at the power lines and it is any vehicle behind, will pull the coax out and check it thx.
It might also be the actual microphone/cord. Not savvy enough to know what I'm talking about, but it's a thought.
I'm assuming that everything is screwed in properly and tightened - ie no loose connections?

It does sound very odd that you can hear clearly and but they can't hear you. Are you sure the person you are talking to is not just taking the %$#*. Is it with the same person everytime. Do they know how to use their gear. Is the problem with their gear. Even a little cheapo handheld is going to be able to go 20m in most situations.
If you are convinced that it is a problem with your gear the next step seeing as how you have already done the antenna (you did get the correct type for the terrain and ground indepedant?) is to check the coax. One of the connections might have come loose or they might not have been done properly in the first place (it might pay to do some fresh connections) or it might have gotten damaged somewhere.

Sorry if i asked stuff that was being answered while i was typing. Even though it is just above the roof line it should still be okay for the convoy distances you are talking about. Yes i know the higher the better but in dense bush having it too high is only going to mean damage.
Like Rosco said make sure everything is tight.
yes thanks guys, will pull the coax and check everything, its different people all the time, they can hear interference but not here what we are saying. need to check the whole setup and try from there. thanks again
