Mount it high, not through the roof but on the gable ends on roofline- lessen the chance of leaks. Theres a few websites you can enter your address into to see how far you are from the source broadcast antennas. Thats going to determine your signal strength. This has an ideal range of 60 miles but realistic, probably 40-50. The longer the cable length from the antenna to the tv, and the more times its run through splitters, the weaker the signal gets. You might need to add an amplifier to boost the signal strength.
