Since you have more than duct tape, use the internet to read up about Wifi, IF that's what they are using. You'll first have to determine what GHz they are at and what receiver and so one, but may I offer some advice?
Lighting is very unkind to such things (and people.) Don't put you or your stuff at the top of the tower. That's for the lightning rod and the cable down to the big old ground lugs. Next take extreme care that if the tower topples, it won't land on you, the house, anything you cherish or some 400KV feed line.
Best of luck,
