I attached 3 antennas to a DP34. The switch is attached to a VIP211. After making all the connections, I did a 'check switch', it went through all 38 steps and all was fine - for an hour. Now, the receiver doesn't see the switch at all. I connected one of the antennas directly to the receiver and it worked perfectly. I also tried unplugging the receiver and starting from scratch, but it still does not see the switch. Next, I tried connecting only one antenna to the switch, but the results were the same. Any help out there?
