I have an interesting problem with a SWM 16 and 2 4-way splitters. I'm attaching a picture of my setup but basically I have a Slimline dish going to a SWM 16. The SWM 16 feeds two 4-way splitters. I have a D12 (PI for SWM 16 is on this run), R22 and H24 on the splitter coming from SWM1. I have 2 HR-24s and a H24 on the second splitter coming from SWM2. I also have a 2 way splitter in one of the runs that feeds an HR24. One leg goes to the HR24 and the other one to a DECA that connects to the router. The problem: If I move the HR24 going to the 2 way splitter from splitter 2 to splitter 1, I lose all satellite signals on splitter 2 (H24 and HR24 show 0s in the signal meter and the 771 message). If I just disconnect the HR24 receiver but don't connect it to splitter 1, splitter 2 continues to have satellite signal. I have disconnected all runs to the splitters and disconnected the PI from the wall hoping to reset the SWM configuration but that didn't work. I have also connected a receiver directly to SWM2 (bypassing the 4 way splitter) and no satellite signal on SWM2 if I connect the HR24 to splitter 1. If I move that receiver back to splitter 2, everything is fine. I must add that the cable run for that HR24 is the longest in the system, about 100 ft. Splitters are about 35 ft away from the SWM 16. What could be causing this problem? I'm puzzled by this. I originally had 2 8-way splitters but noticed immediately the high loss on these 8 way splitters so I purchased 2 4-way splitters from Solidsignal. When I had the 8 way splitters I could move receivers anyway I wanted, well except for the one powering the SWM 16. I'm new to Directv so I'm still learning abut SWM, DECA, MRV and how everything works.
