A friend moved into a place that has an unused satellite dish from the previous owner. She gets poor HDTV over the air signal from an antenna inside the house, but where the satellite dish is now has an excellent line of sight to the transmitters.
There are 2 wires that run from the dish on top of the detached garage onto the wall of the main house, where they appear to simply run through some sort of connector on the side of the house, and then a different set of wires disappears into a wall. I can’t tell for sure without a ladder, but I’m guessing these are coax wiring and they run through the walls of the house into the coax jacks in the walls. Is that how satellite wiring works?
If that’s the case, could I simply mount a TV antenna near the satellite dish, unplug the coax cable from the dish itself and into the antenna, and presto, over the air HDTV signal comes out of the wall coax jacks?
