I run legal limit on HF and 300w on VHF I have DTV off the air plus Direct TV 4 LED/LCD TVs + 6 computer monitors all of them in same room as shack except for one laptop.
In one instance that do have any problems and it is with a new 60" Sony wall mounted in the living room and that is on 20m only. What it does is bring up the menu screen on the TV when I transmit that's it and at legal limit only then.
I do have yagi's for all bands 40-440m and a vertical for 10-80m and also a wire for 80/160m.
I think it is in your neighbor's system if so and you are legal he must accept it legally but it's better if you can work with them.
Good Luck and lots of good DX.
