I was in a hurry, so I ordered a two port FTA LNB on Amazon - the Starcom SP-3602 MINI. I spent over an hour trying to get signal on a dish that was already peaked in and operating perfectly. I had two single port LNBs that I could drop in and get signal within SECONDS. But nothing with the dual LNB. I even took off the bracket, and tried every conceivable angle and location near the focal point. Is it just a bad LNB? It did show background noise when connected. I'm peaking with the AI Turbo S2.
