I would never mention radio shack on RC but they have A great HD antenna
Cat no. 15-1982. it cost 49.00 but works great. I do not get local HD channels in the south FL.area so this should solve your problem.

Note: I have Direct TV HD but it is not available in south Florida yet. I also have CATV. they supplied me with the HD8300. Now I have my local HD on my Main Theater.

The R.S. antenna is still a great option.
