The graphs of the signal strengths at the edges of these dropouts is

Could not access this page in Firefox.
These pages.
dropout.pdf and dropin.pdf sorry if my use of the bash syntax confused
you.
Thanks.

It has. I plotted the location of the satellites in the sky using S/N
bands. I can see the whole sky (ie sattelites are tracked across the
whole sky-- except for a hole in the northern sky where I guess the
satellites never go as viewed from Vancouver.) There are some trees to
the east, and they seem to reduce the S/N by about 10dB but they are
still visible and tracked even through the trees. (Cedars)

Mine are stuck to the iron flashing around the top of the building--
about 1/2 a meter wide. But that flashing is not attached to any
microwave noisy source AFAIK.
The correct URLs are:

You should not be seeing a gap like that. You could get down to a small
number of satellites, but not none. What was the duration of the outage?
I did mean to ask whether the receiver board itself was in a well-screened
box, and the whole assembly properly sealed for outdoor operation. I take
it that you have not extended the lead from the antenna puck to the
receiver board?
My gut reaction is that if the antenna puck is outdoors you should be OK
(unless you were at ground level and blocked by skyscrapers). I hope you
can locate the source of the problem.
Cheers,
David
