I used a slimline 3, multiline (even though I only connect to one tuner). The system is a HR20 using a B Band Converter. All worked fine until a storm in TN blew the dish over. Since then "No Signal". I suspected the lnb was damaged or the dish bent, although both still look brand new. I made use the HR20 was ok by connecting my 18" dish, works great. Next, I swapped my LNB for the old one that came from my house when I upgraded to SWM. I got the same results, I then decided the dish was bad, so I got a used dish with a SWM kit (LNB, PI, and SWM splitters). Guess what, setting it up as a SWM, I got the exact same error or got error the SWM not detected. I swapped the SWM LNB and removed the PI and setup the system as multiline. I connected the non SWM LNB, B Band converter but still No Signal. I tried the exact configuration using my original Slimline 3 as non SWM, just to make sure. Well, it too reports No Signal. I can take my 18" and basically throw it on the ground and get a descent signal.
So SWM or no SWM I can't get either Slimline 3 dishes to work. I can only get my 18" dish to work. I have read as many posts as I can find but I'm still at a complete loss. Any thoughts or suggestions would be appreciated.
