to keep my CB out of neighbors LL?
I've heard a few good things about these: Modem filters - modem filters online - affordable telephone rfi filters
(And here I'm assuming that LL = Land Line = telephone). The telephone should have a Part 15 label on it, indicating that it must not interfere with radios and must accept any interference from licensed radios. Since CB is an unlicensed service, however, Part 15 is out the window.
Take the advice and put a coil BalUn at the stick. That will keep your coax from acting like some of the antenna.
Those who tell you no filter on your end will stop your specific problem are correct.
Like HiDef says, the loop may prevent feedline radiation and IF that is the problem then it MAY solve the issue. If not then the only answer is a filter on the neighbor's phone line. Solving RFI issues is :headbang :bdh: at best most of the time. Been there, done that, almost wrote the book on it. :laugh:
My antenna and radio are grounded.
That could be your problem.
What hidef said, the balun.
Perhaps your antenna doesnt have a good ground plane (the 2nd half of antenna).
Could be its trying to use whatever metal antenna is mounted to, and is wasting RF energy where you dont want it.
When I had my DSL installed they gave me ph filters...I wonder if they would work?

...My neighbor is not upset...he said it only bothered an old wall ph they had in the kitchen....that it did not bother the tv or any of the cordless phones.....I can key down my cobra 148 with my cordless ph here on my desk and it does not make any interference at all.....
well, there's your answer,............... give your neighbor your cordless and tell him to throw his old phone into the chit can
