Actual Signal Elevation

[Spicoli]

Hi all,

This is a question about the actual angle of elevation of the sat. signal. i know the elevation for the dish should be set to 39 degrees for my city (Milwaukee, WI). But I was wondering if the sat. signal is coming in from a steeper angle and then reflected back towards the lnb's at another angle. I've never seen this question asked in any dish alignment thread before and it's got my curiosity. If the signal is coming from a steeper angle, approx. what angle would it be for my area? There has been a lot of question concerning trees and other obstructions and i was wondering if there was a tall tree in the way of the signal if I knew the angle that the signal was coming down I may be able to mount the dish on the ground and have a line of site beneath the branches.
Many thanks to everyone in advance! :)

The arm holding the LNBs does not appear to aim directly at the satellites because the reflector offsets the angle. Different dishes have different angles. Set the dish for 39 degrees and you'll be OK as long as there is line of sight.

The angle they give you is the actual angle and the dish markings are adjusted to align the dish to the proper configuration for receiving it, so if you are trying to get a tough line of sight, you can use a protractor on a torpedo level or use a plumb bob to line up vertical to sight out the angle
