I've been a FTA hobbist for over a year. Circular and KU bands.Largest dish 31 in. . Today, I obtained a wire mesh 90 inch with an AStro Pro LNB. model 2020cs.,with a super jack actuator, 24 in..Where o I go from here? I'm useing a Neusat 6000, which is being used on my 31 in. dish W/LNBF.To check the LNB, if it has a problem, will it damage my receiver [STB]? Also noticed two heavy wires, red & black, also two smaller wires, probably 20 guage, what are the function of these wires? It also has a servo motor attached to the LNB. Any help will be appreciated, Thanks, Larry
