If your intent is to get the 4 networks in HD and you are not trying to get a certain area for sport related programs, then move where you can currently get a signal (61.5 or 129). As far as being obvious, who do you think it would not be obvious to? When you give a different (out of state ) address and keep your current phone number, not being obvious just went out the window. Of course E* knows what you are doing but so far they have played it as a "don't ask, don't tell" thing.
Getting the SD versions of those HD channels, for most markets, is a different story. That takes you being able to get the spotbeams.
