I am looking to buy an antenna for OTA reception of HD only. I was curious if anyone could offer any antenna recommendation. I would appreciate any recommendations I can get from someone who is an expert on antennas or those with exeriences similiar to mine: 1) Looking to pickup OTA HD on UHF and High VHF (I know that Chicago WBBM-DT is on VHF low, but with all the issues with WBBM-DT not worried about it - beside they are moving to High VHF at some point). 2) All stations I care about are in one direction (40-41 degrees) (will let go of the few in Gary, IN if they don't come in). 3) I am estimating that I am 40 miles away. Using AntennaWeb.Org and put in a multi-story building, all the HD ( -DT ) stations that I care about show at Yellow or less. (WBBM-DT in Low VHF shows in Green along with a bunch of SD stations.) 4) Due to the orientation of my home (front faces toward the antennas), I can't place an antenna on the 2nd story on the outside. I can place on the 2nd or even 3rd story in an attic but these are my least desirable option. For these reasons, I was wondering if I could use one of these smaller "rod" (example - Terk TV55) or "flat panel" (example - Terk HDTVs) type antenna on the first floor outside in the front or even if they might work on the back of the building with the roof in the path. Or would an inside one work? Or do I need to use a "large, wire type" mounted in my attic? Any recommendations out there?
