I switched about 6 months ago from D* to E*. With D* i had their antenna they send with the their HD receiver and i was able to pick up locals via OTA. now i have the 622 and have been unable to pick up any channels via OTA. when the D* installer first brought out the antenna and receiver he said the receiver amplified the antenna strength. not sure if the 622 does this or not. any ideas on what the problem might be? by the way i'm about 50 miles south of atlanta, ga thats where most of the towers are
