I have had great success with low-cost band pass filters from InDuComm. They
have been low-cost and very effective. They also sell a full line of TVI
related filters which I have had no reason so far to try. Based on my
experience with their band pass line of filters you might want to check them
out. I have a link to their site on my webpage on the ' Ham Radio Links'
page. BTW I totally cured my in home TVI ( on cable) with 2 of the Radio
Shack snap-on ferrites placed on the cable right at the TV set. Now I can run
800W on any HF band and my wife watching TV doesn't even know I am on the air
even though she is in the next room from the shack. They really worked great.
Hope this helps....
