Or, the dish was installed before 99 and 103 were in service. As the dish was on the house when I moved in in early 2007 and as the 99 and 103 satellites went into service in 2005, it's entirely possible that it was installed according to policy at the time.
A situation like that isn't quite possible if following the policy... Here is an excerpt from the DirecTV SPIG (Standard Professional Installation Guide) Section 3.2:
3..2 Unobstructed Line of Sight
Use a compass and inclinometer to locate a site with an unobstructed view to the desired satellite(s).
Ensure that you have a 10-degree window around the charted location for the satellites. Remember the optimum
window is for clear LINE OF SIGHT (LOS) from 10˚ left of the 99˚ satellite to 10˚ right of the 119˚ satellite. This is
~ a 40˚ window. If you only require LOS to the 101˚ satellite and the window will not allow the full 40˚clearance, it
is acceptable to proceed with the installation. Take into consideration future growth of trees that may impede the
signal. If you cannot get a clear LOS, call your supervisor.
DirecTV has always required a 10 degree window in its policy to accommodate for possible new satellites, tree growth etc. Yes this wouldn't have accommodated the 119 back in the day so lets throw out that counter argument now... So, the argument that a 101 basic dish was installed within policy at any time and now can't get 99 or 103 isn't possible unless there is new tree growth/building/etc. This policy also includes LOS variance below satellite elevation, although it isn't expressly written here. Example if the elevation to the satellite is 45 degrees for your market you need clearance at 35 degrees elevation to accommodate possible growth, although fixed objects like buildings tend to rightfully get ignored for this part of the policy. With that said, odds are the use of the 10' poles to clear trees still weren't within policy even when 10' poles/tripods were allowed.
