Looks like WLEF is pretty easy to receive from your location there with about any outdoor TV antenna. As for the rest, I'm not putting much hope into a simple solution. The signals drop off fairly quickly for the remaining channels. Costs may add up but consider that it's a one time cost compared to monthly sat service. The downside is that you may spend several hundred dollars and in the end, not do any better than a $30 antenna to tune WLEF.
You'll likely have to use a rotor to go after the other channels as needed. You'll want a large directional antenna so that you can pull as much signal as possible. A rotor will allow you to get spot on to the direction for the highest signal reception. But be prepared that your results may not be acceptable. The signal strength numbers reported don't exactly lean in your favor. The days of snowy analog reception are pretty much gone; digital reception that drops out will frustrate you very quickly.
Trees will impact reception even further, so be sure to evaluate each direction from the mount point. You want to see as much horizon as possible in the direction of the signals.
There's always the extremely simple solution of a good book!
