From ground level is how you measure. you can plug in different heights in tvfool to see how it affect signal strength.

Yes and REMEMBER, the higher you get it so there is nothing in the way, the better . You want to get the clearest path you can possibly get so the signals hit your antenna.

XG-91 is the model # of the antenna he's referring to. It's good for deep fringe areas and you can tilt it to get over the topography

but how accurate is tvfool really with those heights? Do they actually factor in things like trees and houses?
