This unit worked better for very weak signals , all 50 plus miles away, even inside at the
end on 70 foot of coax from my antennae . I was only getting 7-12 channels with a pre-amp ONN and a $75 Channel Master mounted at the antennae mast. I sure would much rather hook an amp behind my TV than climb 3 story roof wouldn't you ? This ANTOP gives me 32 decent channels.
