I was correct...
I'm afraid you've misunderstood the myth.
The myth isn't about whether a
reflector dish is used, the myth is, that because of that,
satellites are actually higher in the sky than the elevation settings.
I'm not saying that we don't use a reflector dish-with offset LNB (what would the reflector be for???), what I'm saying is that the
satellites are NOT higher in the sky because of it.
The elevation scale, that is built into the dish design, takes this into account. So when you point the dish at say, 40 degrees elevation, the dish, using its "reflector", is precisely positioned to receive a signal at 40 degrees elevation. Because, that's where the satellite is.
So could it be a mistake to think like SmityWity when you're considering line-of-sight? You can see how it affects his line-of-sight judgment. But, it's not his fault. I was told this in a DirecTV training class! I found it interesting and set out to find that "magic number", the "abt 20 degree add". I wanted to be sure to get those birds, and supply Better TV for ALL!!!

Here's what I found:
The satellites ARE at the elevations stated. NOT plus some unknown number of degrees. So when you take your clinometer out to check for line of sight (you do use a clinometer, don't you? Trust your clinometer. Learn where your birds are and trust your clinometer!), what elevation do you check? !sadroll
If you're smart, you'll check where they say they are.
If you research satellites, azimuth and elevation, clarke belt, skew, and geosynchronous orbit, you can find your satellites. I did because no one, I knew, could tell me the answers. You can find most of it here:
