Just got a new Panasonic 42" plasma and am anxious to get HD programming. D* is coming tomorrow to install my HD DVR and OTA antenna. What is the distance that HD programming can be received, assuming flat territory? I am about 70 miles south of Richmond, VA, and currently receive local channels from there. Will I have a problem receiving HD with the OTA antenna at that distance? Are boosters needed with OTA antennae? Final question: D* says you cannot get network programming if you are getting locals, and that locals rarely, if ever, give their permission for the networks...what then is my option to get HD programming if my OTA is not sufficient?
