Query: HDTV signal so-so

I live in a brick constructed house in the NY Metro Area. Only Channels 5 & 9 come in clearly in HD mode; other major networks do not even register after a Scan for HD Channels. Antenna is fairly large with the rabbit ears extended(not noticable in photos). Make sure tail piece is fully inserted past the marking to receive HD broadcasts.
