Chester,

You may be able to use the existing cable but all the setups I have seen recommend an ultra low loss cable.

I am going to use my existing repeater which accepts a RP SMA male antenna connection. I will run new cable. The existing access hole for the sat dish cables is directly overhead the TV so it's not a tough job to run new cable. I have to get on the roof to install the antenna on the old braund mast.

Yep a new controller is around two hundred bucks. Yikes. Now that I have the schematic I am going to use a auto window switch to see if I can just get it to go up and down. Stay tuned.
