hi

thinking about getting into sat's, and have a newbie question

i may only be permitted to put up my antennas on a part of the roof that
would be blocked by a structure(elevator room)

so in 1 compass direction or so to almost straight up i would be blind

question:

so is their a particular compas headding that is best to loose?

It MUST be a direct view from the antenna to the sat. Otherwise is it
just to forget it. With analog reception, the antenna can work very
well through a glass window, or while directing the antenna on a
reflexion (at least if you can afford a high end tuner in this last case),
by but with digital reception, even a tiny glass will cause a
lot of trouble (some channels will just disappear), because the digital technique use phase multiplexing
and the phase of the signal will change in a non linear fashion through
the glass or on a reflexion.
