Got a Directv HDTV tivo and hooked up the antenna thats connected to the wall plate in my apartment to get ota locals in HD. Bam... Ground Loop hum. Never had the hum till now. I figure the antenna installed is grounded at a different location. It's not as bad as I've hears some others before but definitely noticable and bad enough to warrant a fix. Anyway, whats the best way to go about fixing a ground loop with a passive antenna?
