Passive TV Repeater

In a nutshell:

Get three directional TV antennas.
Go up to the mountaintop.
Point one antenna at the city where the TV stations are located.
Point the second antenna at your house down in the valley.
Connect those two antennas together with a coaxial cable.
Go down to your house and point the third antenna up at the one one the mountain top.
Connect it to your TV and see what happens.
If it doesn't work, try putting an amplifier between the two antennas on the mountaintop.

Wonder if it would work...

I will guarantee it will work. The question is how well. If you have power, then a wideband amp between the two antennas topside will definitely help things along. Ever notice the old "flyswatter" antennas on microwave towers with a dish at the bottom of the tower pointed up at the "flyswatter"? Passive antennas can work. Keep the coax between the two antennas as short as practical. The amp can help a lot here. make sure the two short range antennas are accurately pointed directly at each other with as much gain as you can practically afford.. yeah it will work. If the signals at the top of the mountain are as good as he thinks, this should do it for him.

I would try the totally passive antennas first, then add the amp if needed. The reason is less complexity and more lightning resistant. Very little investment for a potential high reward. On the antenna pointed at the house, be sure to depress the elevation to point it exactly towards the house as near as practical.
