re fine tuning DirecTV new SWiM SL3 LNB and slimline dish
I think I've got a handle on dialing in the Azimuth and Elevation, but the tilt adjustment for the dish is the most crude adjustment mechanically on the gimbal. With it's 3 carriage bolts and stamped steed loose-fit circular slotted holes, one can put the dish's tilt several degrees different while the degree pointer remains at the at the same place (just by taking up the slack in 2 directions).
So since it's not a fine tune parameter in any docs I've seen, I gather this adjustment isn't that sensitive. I understand these LNB's use circular polarization so "skew" isn't an issue, but "tilt" is still important to coincide with the virtual line between the 3 sats.
For an OCD engineer like myself, I'd like to adjust it best I can. I've got a tree that will eventually creep into the edges of my LOS, and the wife gets bent when the signal goes out due to storm, so I'd like to maximize it hoping to minimize signal loss, and get the best quality I can. My dish is easy enough to get to, I've got way more time to fiddle with it than an installer would, and I don't mind.
Is there a good procedure to fine tune tilt? I don't mean the way to do it physically, I can wrestle the fine adjustment itself, I mean procedurally. As in "... go to this sat and adjust, then that one, etc...." Or is this so insensitive that it's a waste of time? Just set it using the dish's inaccurate tilt protractor and forget it.

Thanks!
