Here are some options.
Do a search for "antenna(s)", or "OTA", or "UHF", etc. in the HDTV Hardware forum. There is a ton of information, even including how to design your own custom antenna.
Other resources for antenna selection are:www.titantv.comhttp://www.antennaweb.org/antennaweb/step1.html
IMHO, the best way is to rely on existing HDTV veterans by posting a topic that specifically asks about OTA reception in the area where you live, as opposed to a topic that has no specific information, ex. HDTV.
This forum can be of great help, if you use it properly.
Thanks for participating.
