I have just bought a quad LNB off Ebay, and have tried to fit it myself, I made a not of the orignal postion of the old LNB and wired up the system before taking it out, made all the connections to the Digi box and strung the cable to the dish, then made the connection at that end.

I then made the switch of the LNB's, now this is where I am having the problem, I rotate the LNB clockwise so the connectors are at about the 7'o'clock position and keep checking that I only move the LNB very slightly to see if I have a signal, but low, and, behold, nada.

Any help please?

David.
