EDIT: Got through to someone at Audivox Tech. The 1a is wall mountable. The 2a isn't. That's it. Only differences.

For anyone else that may stumble on this, I hope it helps! :)

Yes it does. I was wondering about the performance?

Its like the RCA ANT1500 and others in that series.In other words, not that great on UHF, stinks on VHF.
