You should not be having any problem with your neighbor that is
using cable!  I run 1.5KW and my home TV is in the next room.
It has cable TV and I get no interference!  Do you have cable? And if so,
do you have any TVI ???

I would suspect that her TV cable connections are at fault!
Probably one of the "F" connectors is bad! (No Ground).

Good Luck.
