I live in the mountains in Southern Utah. I have a good view of the transmitter site for OTA digital reception (25 milis away) so yesterday I hooked up the old antenna (15 years old) and pluged it into my 622.......................BANG I am able to receive ABC HD OTA with the antenna laying on the front deck!!!! My signal strength is 64. My question is, is a signal of 64 strong enough to work with an indoor antenna. I really don't want to get up on the roof and route some new coax all over the place.
