Here is a roof mount that will get the antenna higher ,

I think a Winegard HD7082P antenna with a Antennas direct CPA-19 preamp , mounted on a Channel Master CM9521A rotor , mounted on the 10 foot tripod will get you the tv stations down to and including WENH-TV 11 PBS , and good a posibility of a few more on down the list.
