DTV Antenna Recommendations

[toxcrusadr]

My sister and my mom both live in houses in Albuquerque and don't have cable. The broadcast antennas are all on a mountain 5000 ft. above the city in direct line of sight. 60 mi. away to the north is Santa Fe with a station or two. They are both having problems getting DTV stations to tune sometimes, the kind of troubles mentioned in the "DTV Woes Continue" thread. They are not handy people ready to go up on the roof and make major renovations. I know mom has an old TV aerial on the roof pointed right at Sandia Peak and she still has problems. Not sure what sis has.

Is there anything they can use indoors (i.e. easy to plug in) such as a powered antenna or an amplifier, reasonably priced, that actually works? Someone mentioned the Channel Master UHF antenna but it's out of production and I'm not clear whether it even applies to digital. I could *possibly* install a new roof antenna when I visit, but what else can they do?

Help!
