Our Classic Arts channel is very popular and we quickly hear about it when it goes down. Thats just what happened the other day so I went up to investigate. The receiver was showing no signal and of course no lock. Now this signal comes from a dish on the roof that is held in place with cinder blocks, so thats the first thing I checked.
It’s easy for someone to bump into the dish and move it slightly and we then loose the signal so the first thing I did was check the pads to see if they looked like they’d moved. They all looked fine and just where they had been.
Next I grabbed the dish and tried to move it, if a bolt had come loose then I would be able to steer it a little either up & down or side to side, but it was pretty solid.
The LMB could have gone out but thats rare and I would need a spare one to test for that. The last thing I could check for while up on the roof was the coax cable, we had moved the dish months before and had to extend the cable. When I found the barrel and tried twisting it, they turned! Not a good sign. I opened it up to look for signs of dirt and then used wrenches to tighten everything together.
When I went down stairs I was looking at Classic Arts, the signal was back and at a good level.
