Well, let's see... several of my "fun times" I have already documented on this site, for example:

I also have documented another one of my dish moves (I am better at them now, realising it is a prime time for a brain error) involved a minor cabling error which resulted in "hours of fun" to try and correct (until I realised what stupid thing I did)! A couple of years ago I went to move a three LNB dish, labelled and removed two of the cables, moved the dish, reattached the two cables (wrongly reading the labels it seems), and spent "hours of fun" trying to re-point the dish (got a lot of exercise going up and down the ladder). Could not figure out why when pointing and peaking any of the LNBs did not bring the others in. As well, on the centre LNB (really one of the outside LNBs) the signal was way down (so, naturally, I'm thinking that the move brought an obstruction in to play). It was only when I was just about to move the dish back, that I looked at the cable labels...
And, finally, we come to my "disaster" dish (I have other names for it, but they are very rude). It has been a real treat from the beginning. Bought it early on a Saturday, put it together, started doing hand held tests on the ground, wasn't getting levels I expected to get. Looked at the dish and realised there was something strange about the LNB arm. Since I have another dish of the same make, I take it over to it to compare, and realise the store gave me the wrong arm for dish (it's way too big). Back to the store, find out that they sold the larger dish (with my arm) not too long after I bought mine. They didn't have a spare arm, I had bought the last 80cm dish (they expected a new shipment on Monday). Figured that the person who bought the larger dish would realise the error and be back soon. Went home and waited for a call, it didn't come. The store isn't open on Sunday, so I stewed the rest of the weekend. On Monday, waitied for the call, it didn't come, so I called them with about a half an hour before they closed. My arm had not returned, but the new shipment had arrived, so I got a replacement. When I get home, I realise the arm was not for that make of dish, and was slightly different in hole placement and length, but I have a drill and hacksaw, and used the other dish as a template. I was not going back to the store the next day!
That was only the start of my troubles with that dish. Five days later, it decided that on a nearly windless day that it would sail off a low-slope roof within minutes of when it would be re-mounted on the pole (after I had added an extension). I grabbed the coax trying to stop it, it pulled the coax connector port out of the LNB, and bent the arm and slightly warped the dish when it hit the ground (at least it didn't pull me off the ladder, but it did try). As well, in the end, no matter where I tried to mount the dish, I never could get the satellite I was try for, and had to settle on some back-up satellites.
During the late winter/early spring this year, I noticed it was losing signal and had to keep lowering the elevation a touch. It was only when I kept comparing it to a dish pointed 2 degrees different that I realised something was really wrong. On examining the arm, I noticed a bulging just past the bend heading towards the LNB, and found no hole had been drilled to allow water to escape, which, naturally, had frozen and bulged and bent the arm! Took it down, lined the arm up against that other dish of the same brand and re-bent it, and everything is now fine (and I also drilled a hole in it).
As I said, it is my "disaster" dish... I wonder what it's thinking to do next to annoy me!
