Antenna selection is not that easy. What works great for me may not work for you. You don't list your location so we can't do any work for you. Go to antennaweb.org and follow the directions. When it comes to elevation, put in 100ft. (the site is very conservative on digital stations and this height better represents real world results). Finally, copy/paste the results back here. If you are only wanting digital channels, then please only paste those.
