i'm still under contract with Comcast for my Blast Plus package until May/June 2015, but with the encryption of basic channels and the promise of a free HD box for at most 6 more months, i spent the holidays installing an OTA antenna in the attic of our town home. i am pleased to report that i pull in every single station indicated on antenna web within 50 miles including the critical networks FOX,NBC,CBS,ABC,PBS,WB, and much more.
wish i had done this a long time ago, but the recent encryption was the last straw since it required using a Comcast box for fee (ultimately) and removed my ability to record TV shows on our computer. (poor man's DVR)
anyway, i am reporting this because i had doubts an OTA antenna would work in the attic of our newish (2006 construction) town home 36 miles from the Sutro tower, but its all good and wasn't too hard to get working.
if anyone is curious, i installed the Channel Master 4228HD.
