I get my OTA over QAM through comcast so reception isn't as much a concern.
(though has its own issues, like dealing with poor signal quality in
the Condo building I live in. lots of students rent condo's and this
last move-in weekend saw a signal quality drop, which means one of the
Comcast technicians f'd with my cables, now I need to see if I can
undo this work without having to call another technician out.
thankfully the closet is just around the corner from my condo.</rant>)
