I want to upgrade my old GME TX830N 27 MhZ CB radio - partly because I have lost the aerial and partly because it had a very limited range.
Should I get another 27 MhZ or a UHF radio.
What do most MH'ers have and why?

Hi Angela, This has been discussed a few times on here in the past, but it's not easy to search for them as the search facility on here won't search for 2 letter words like cb :?

But below are a couple of threads i did find about cb radios. ... nel#p91546 ... dio#p80503

We have a 27 MhZ cb in our car when we are away with the caravan. We use channel 24 when travelling with others, and channel 11 to talk to truckies. And have it set on channel 24, and scanning channel 11, so will hear anyone on either channel. I am sure truck drivers appreciate hearing from us slower drivers so we can tell them that yes we know they are behind us and will pull to let them past when we can. On a road we are not familiar with they can often let us know when a place to pull over is coming up.

If your one had a very limited range, it was probably due to a problem with either the aerial or the coax lead from the aerial to the cb radio.

Having not used a UHF cb on our travels, I'm not sure how many others on the road use them. It seems that truckies have the other ones in their trucks, and so do lots of motorhomers. But I have heard people say that they never hear anyone on their cb, so they leave it turned off! :lol:

Hope this helps, Angela.

Hi Angela

Stick with CB. UHF is better suited to, two motorhomers traveling together. Andrew and Debbie are right on the right track. If you want to talk to someone CB is the way to go. Your limited access maybe caused by having the wrong type of aerial. Get a qualified CB person too install your new aerial. Its something to do with something called "ground plain" . If you can't stick it right in the middle of your roof, then you need a special aerial, that has its own ground plain. It has a coil wrapped around it, somewhat dearer, then a simple little wire aerial. But it works real well. Reception depends on the ground terrain or topography.

Cheers Trev

Or you could buy a dual unit with both UHF and AM CB on it :)

Busrsq could you please let us know thew model of you CB and where you purchased it. A combination unit would seem to be a good option if you do not know which system to use.

re the combined am and uhf cb radio. What sort of aerial are you using with that unit? I don't know too much about it, but i do know with the am sets aerial tuning is critical to them working well and transmitting over a reasonable range. And that uhf sets are on a way different frequency, so wondering if it needs two different aerials to work well?
