Lets see if I understood, you're not willing to spend 10 mins getting your dome Sat antenna pointed at the right Sat, but you're willing to spend hours up on the roof covering it with tin foil and tying a string of soup cans from one end to the other?
It doesn't take a rocket scientist, I'm sure there is an example on YouTube or Google. But your question reminds me of that redneck rocket scientist that used to do things like convert a perfectly good pickup engine to run on cow manure. made for some entertaining TV but not very practical.
If you're more interested in a cell antenna & amp than getting your TV antenna to work, just go buy one; they're almost as cheap as tin foil & soup cans and much more effective.
PS: Most of the Sat dish related homemade cell or wifi amplifier experiments I've read about use a discarded full size open face Sat antenna dish with LNB arm, not the small rotating type hidden inside your dome.
