My suggestion would be for you to try with the following
stipulation: Whatever you purchase can be returned,
undamaged, for a full refund. I no longer recommend
the Winegard Antennas. The failure rate of a connector
is so high, it makes them a poor choice. You might want
to consider:

It is a very good buy and you should be able to return it
at any Home Depot.
I hope your roof is NOT metal. It can cause all kinds of reception
issues.
With 50 feet of known good/new RG6, connect the antenna to
one television through a door or window. One person at the Tv
and the other, holding antenna on the roof. Try various directions
and also try tilting UP towards the tops of those hills as well.
GOOD LUCK and Be safe on that roof!
