One thing I've learned about satellite dishes having worked with them in one form or another for 30+ years: don't put them where you can't reach them for service or failures.
Perhaps 80+ feet up a tree isn't totally out of the reach of service much of the year, but I doubt it's serviceable in January with snow and ice on the ground and the trees. Florida would be an exception, although thunder and lightning storms would seem to pose their own problems.
