Media for wifi antenna in the mountains

wifi antenna in the mountains

I've spent a dozen hours looking for a solution to my situation, and I'm only finding parts of the answer. Here's the deal.

I live in a beautiful canyon 4 miles from the valley/city. A peak 600 feet from my house has line of sight to the city where there are WISP towers. Likewise, I have line of site from my front door to the peak

600 feet away. I can build a biquad antenna and put it on that point and it receives a signal (tested with my laptop), but I'm stuck after that.

Obstacle 1. There's no electrical power plug on the peak. a. I'm not comfortable running power/conduit that distance (and I'm sure there are ordanances against that) b. The distance is too far for Power Over Ethernet

Obstacle 2. How to get the signal from the bi-quad to my home: a. The distance is too far for Cat5 cable, and there's no way to power any in-line repeaters b. I could run fiber cable, but that requires power at the antenna c. I could run old ThickNet 10-base-5 cable, but that requires power at the antenna

So, a couple exotic ideas I have: Is it possible to build a bi-quad that captures the signal without power or only with simple batteries, then use a cantenna at my house pointed to the bi-quad? Can I build some sort of reflector on the point such as a mirror or metal sheet, then locate the bi-quad at my house and point it at the reflector?

Are there other viable options? Looking for some creative ideas here.

Thanks in advance
