[mythtv-users] HDTV antenna quandry

[Mark]

Maybe one of you guys has run into this before...

I'm planning on moving to HDHOMERUN boxes in the near future, but I have 
a dilemma.  I have multiple stations nearby, Lansing 30 miles to the north,
Kalamazoo 45 miles west, and Detroit 60 miles East.  I need higher gain 
antennas pointed in multiple directions.  I could do it with a rotor, 
but then I might miss
a show on a channel where the antenna isn't pointed.  Best bet is 
separate antennas.  Can antenna feeds for digital broadcasts be combined 
with a splitter/combiner?
Or should I run each antenna feed to a separate hdhomerun and play with 
channel/input  priorities until it works right? Currently this is my 
only avenue for recording HD.
Cable and Sat don't carry what I want.

Thoughts?
