Re: CB radio - SWR problems
Sorry to butt in guys, I just want to say that this is a fantastic thread!
I've barely understood more than about 3 words but it's great fun to read nonetheless

In 10 years, I don't think I ever said 10-4.

Re: CB radio - SWR problems
Jeez guys, this takes me back a bit.
Will have to see if my stuff still works, used to be a dab hand at tracking down wave-hogs with my trusty old DV27 on my car.
Does anybody still use AM by the way?
we will have to have a roll call of handles
mine were Sid Snot and Big Sid and used to help run the BTB CB club 20 years ago.

Re: CB radio - SWR problems
Being a huge "Convoy fan", I have always fancied getting into CB radios. Seems a bit more to it than I first thought

Re: CB radio - SWR problems
Eee, this brings back memories.... old ones but good ones.
I still got some of my gear packed in the loft, are people still using the hi/mid/lo bands, I thought they had all changed to UHF now?
What's the chatter like thse days? I left it when it got to just stupid kids playing music all day, swearing etc. Couldn't get a decent conversation in at all. Oh & I got another license...lol
Ther's nowt wrong with a Thunderpole, damn good aerial.

Re: CB radio - SWR problems
dont forget that the SWR will only be great at the middle of the freq range that the ant is designed for.
just my tuppenny's worth, but it might be worth checking at a different freq?

Re: CB radio - SWR problems
Yeah we tried it on super-lo and super-hi (2:8 on both) and the 2:3 is channel 20 on the mid-band.

Re: CB radio - SWR problems
First thing is where have you measeured the SWR?
Swcond thing is NEVER tune the rings until you know what the SWR is.
The best way to check the SWR is to connect (f Possible) the swr to the antenna directly or as short s patch lead as possible.
The reading at the radio ens will be different...its what is at the antenna that counts.
Is it possible to ground the radio in the house?
If there is and SWR on the cable then it will read differently on a different lenght...its a wave after all.
If all else fails...stich a tuner / matcher in line to flatline the swr to the radio / finals see a good match

Re: CB radio - SWR problems
We measured the SWR at the antenna end of the coax. We only touched the rings after we couldn't think of anything else.
We've thought of using a matcher but as he's hoping to use the set-up for DXing, he doesn't really want to lose power.
