|Reception prob - RF Cafe Forums|
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Newbie here,hope someone can help. I live about 2 miles from my NBC affiliate, which would be VHF 12. It seems to effect virtually all my local channels, to such a degree that my fox is completely scrambled and its UHF 35 , and only 10 miles away. The question is would the HDTV stuff( it all being UHF) be just as likely to be shot by this overpowering local channel? Hope this makes sense.thanks.

Yes, HDTV would be affected by the same overloading. The trouble you are having with UHF35, in fact, may be caused by the NBC high def signal, not by channel 12.
Things to try:
1. Call the TV station and ask them to provide you some filters because of overload you are getting. In the past, they sometimes have.
2. Buy an attenuator at Radio Shack that will cut the NBC level and still allow 35 to be viewable.
3. If you feel like tinkering, you can make a "quarter wave stub" filter yourself out of coax cable. See a ham radio book for instructions.
4. Borrow somebody else's TV. I wouldn't think yours should overload so easily.
By the way, if you are running an antenna amplifier, all of the trouble is probably there.

All good advise.
Another option would be to just turn your set off altogether. You wouldn't be missing anything useful.
