you also need to take into account geography between the receiving antenna to tower in a trace from low elevation to high elevation. if there is a bump in between your results will be hampered...signal will be blocked.
at the fringe of reception the only alternative is to install as high as possible with the most powerful antenna and best preamp, cm7777. there are other variables besides curvature that come into play and can not be determined till you install.
in your case would try a 91 xg which can easily be tilted up to try to squeek more signal.
75 miles is at the fringe of signal in most cases and geography does not work in your favor there. you will not realize success till you give it a try.
