We have a low VHF channel (channel 3) and have discovered that if we have our computer power cord plugged into our laptop, it makes the channel unwatchable. Unplug it from the computer, and the channel goes right back to perfect. Any ideas?
By the way, thanks to everyone for helping getting our antenna system working. We have ditched our $70/month satellite and are enjoying our free tv!! Our setup is a low vhf antenna on the roof, cm 8 bay in the attic, both plugged into a cm 7777 preamp, and then split to two televisions. We have also tried plugging the computer into different outlets, and no matter where we plug it in we get the interference on both tvs.
