I camped in Sandwich MA (near entrance to the Cape and got a number of clear analogs on my HH TV. I imagine one could get some digitals (in some limited locations) with an 8 bay bow and amp but one would have to put up an expensive rig and hope for the best. And maybe get the worst.
Back in the 1970's my father in law (who hated cable) put up a very large VHF antenna, a seperate 4 bay bow (no amp), and rotor and had a number of clear stations on VHF. He even had his beloved Ch 3 Hartford for the news from back home. He had all those clear VHF's and he'd watch the 11 PM news on Ch 3. So so reception on UHF. Watchable stuff but not real clear. He was content with the set up. Why no amp on UHF I'll never know.
But this location (Harwich-mid cape) would probably be very poor as most/nearly all digitals are too far away for acceptable digital UHF reception.
