What's the best way to filter out or eliminate RF coming through on normal cable? Neighbor bought a big screen and it's VERY noticeable.

You can buy RF filters but if this is in your cable line you may need to talk to yopur cable provider.

Believe me or not, this worked for me.

Get a 75ohm to 300 ohm converter, and a 300 ohm back to 75 ohm convertor. This isolates the signal, and got rid of awful humbars.

Its a cheap try.
