Very sorry to hear about that incident.
I already removed the dish and J-Pole. I had my wife stay at the bottom of the ladder and stabilize it while I climbed up and unbolted the J-Pole. Fortunately the installer only installed 2 lag bolts (out of 4 possible). Took about 10 minutes and I survived.
... My wife is a retired RN (registered nurse) and said that during her career she has treated over 100 ladder fall victims. But she thought I was OK to do the job with her holding the ladder and preventing it from tipping over.
Anyway, I have attached before and after photos. What you don't see is the messy cable run the installer had going into the house. There was loose cable on my sidewalk that someone could have tripped over.
If anyone wants the J-Pole (photo attached) I will give it away (just pay shipping +$5 for gas driving it to the post office).
