My question is there a way that I could have the antenna at the top of the hill and somehow capture the signal via the internet and access it on my computer at home?
Similar to this idea, I have read, on the internet, an article that describes a small community, down in a valley, in a remote location, that is in a similar situation.

They did like a re-broadcast setup.

They described how they set up a community receiving antenna up on the high hill, and then connected that back to back with another directional antenna aimed and beam (re-transmit) that signal down in the direction of the community - to be received by all down there in the valley - via their regular antennas.

They needed "isolation" between the two back to back antennas, up high on the hill. (probably both physical and electrical isolation)

... and I think a little bit of amplification between the two, to boost up the received signal to be re-transmitted down towards the community down in the valley below.

some of the isolation between the two antennas, was achieved by using directional antennas, and by putting the antennas on either side of the hill peak.

this is like a radio re-broadcast type setup.

this is old stuff, old school stuff, used long ago, used in pretty remote locations - I think - where this sort of setup (retransmission like that) is not likely to interfere with the reception of anyone else - since there's so few others around.

... serving just that little community way down below in the valley, and affecting no one else around - based on the specific situation and terrain.

[ ? like, example, a little fishing village, very remote location, way down in a valley, like an inlet, or fjord, off the ocean, or river valley, with high hills all around, and no signals down in the valley, but signals up high on the surrounding peaks ... so able to do this sort of thing - and giving them the only reception and TV link possible with the outside world ! ]

[ I forget where it was, in the British Isles I think, some remote little town, someone had set this up, long ago in the past, according to what I remember of that article I read ]

FWIW, here is how I would do it.

Head end:
  • Antenna on top of hill connected to HDHomerun tuner(s).
  • HDHomerun connected to 2.4/5GHZ router with removable external antennas.
  • Router connected to high gain directional WiFi antenna(s).
Receiving end:
  • High gain directional WiFi antenna(s) connected to 2.4/5GHZ router with removable external antennas.
  • Router connected to LAN
  • Internet TV, HTPC, media players, etc connected to LAN.

I think you are referring to the Fort St. James TV Society in northern BC that run a licensed, CRTC-approved OTA TV system:

Running an unlicensed system could result in having to shut it down (at best) and legal hassles (at worst.)
