Lovely cabin and wooded area. Looks like a nice place of relaxation.
You are pretty enshrouded in trees. It's lovely for viewing of the foliage but bad for signals. It looks like the trees themselves are 50-75'? It would be optimal if you could get the antenna above the trees via a tower.
If I were installing an antenna here, I might opt for tower to get above the treeline. It's expensive and much work, but you'd be putting your antenna in the best possible situation to receive the signals you want.
Installing at lower heights (20' or so) will leave you at the mercy of the foliage in the summer and could cause reliability problems.
That's good you have 1 TV. From a application standpoint that makes it rather easy once the coax is in your cabin.
