I live in Sheffield UK which, like Rome, is built on 7 hills. My #antenna - a 42 metre long #doublet - drops from 8 metres high to 5 metres high on the north leg, but the end is at ground floor level, compared to the house, because of the slope. But the slope also tilts your ground and, so, the take off angles. These are lower, compared to the actual horizon, than you'd expect from an inverted V - specially on higher frequencies. So I do better than expected into Japan & USA. #hamradio
