needed ATSC for my current project so plugged in the ATSC feed and couldnt get any channels so I went up to the roof to check out the setup. Hard to see from my low-rez camera phone pics but they had 3 different antennas being combined into 1 coaxial plus a directv feed. I assume the 3 antennas where for the 3 different transmitter locations but they where pointing the wrong locations, the setup was tied down pretty well so I dont think the wind moved them. There was a also a rotator for the 2 4-bays but the wire was cut so it didnt work anymore.
