There are lot os diffrences - for one it is warmer most of
the time in Texas.

My point was that you get some E-skip, you get some "tropo/forward scatter
/ groundwave whatever you want to call it" - but you get some more than
others in the diffrent contests but the basic modes of propagation are 
the same and I would chose antenna heights based on that.  

Yeah - they would be fixed in diffrent directions etc. but the 
physics of it are the same for TX or MI.

This has to do with distance from population density not what heights 
to put antennas at to work things.
