I have the opportunity to pick up a 13 ft fiberglass dish with actuator, receiver and amp for free, but I have to take it off the pole. He says the dish is about 25 feet up. I can also pick up a 10 ft. mesh dish (which looks very similiar to the winegard I saw on this site earlier, but it'll cost me $50 canadian for the dish and LNB only. I was thinking of buying the mesh dish, taking down the fiberglass one, and then using the mesh dish in it's place. Is buying the mesh dish worth it, or should I just take the freebie?
