I was installing a multi-switch yesterday and after climbing the ladder to run the 4th cable from the dish I notice a few things that might explain my frequent rain-fade issues. First of all the LNB wasnt attached to the arm. The only thing holding it in was the cable tension pulling down on it. The cables themselves were held to the mast with the grounding wire from one of them. Also, all the cable fittings werent even finger-tight. "Finger-loose" is more like it. And finally, the mast itself was only bolted to the house using 2 bolts, both on the same side of the mounting plate. Frankly, I guess I'm lucky I ever had any kind of a signal!
