I have a similar situation. My TV channels are in about 8 different
directions. Most are in 4 primary directions, 2 of which I can
compromise in the middle, giving me 3 to 4 directions to deal with.
I currently use a Pronto universal remote which has macro timers on it
that I program to turn the antenna at specific times to specific
locations. I thought about having MythTV do this, but the situation for
me is too complex for me to figure out how to get MythTV to do it. For
example, sometimes I record one or more channels from the same antenna
position at the same time, which is straight forward (move the antenna
to that position). Other times, I record more than one channel from
different antenna positions at the same time. Not so simple, since
depending on which two (or three) different antenna positions are
required, I have to carefully pick a different compromise position.
Trying to get MythTV to do this seemed not worth it to me.
The other thing is that it takes time to move the antenna from one
position to another. The amount of time depends on the antennas current
position and the new position. If you are recording back-to-back
programs on different channels from different positions, you have to
decide whether to move the antenna early, and possibly lose the last few
seconds of the first recording, or move it late, and possibly lose the
first few seconds of the second recording. My preference has been to
move it early, since some of my DVRs will drop the entire recording if
it fails to get a signal lock at the very beginning.
My long term goal is to add additional HDHRs connected to separate
antennas pointed in the fixed directions and configure them for the
channels each receives. This way, the problem goes away completely.
