... I found a pic online that looks right; it's a 1m Primestar dish. I
cropped out just the dish - here is the link:
... I have previously been using an old round DirecTV dish with various
home-made and purchased antennas to receive Inmarsat and a few other signals
but obviously needed something larger to experiment further. Both Vivaldi
and patch style antennas have worked well with the DirecTV dish. I'm not
completely sure what I will do with this 1 meter dish, but I don't have any
plans for tracking at this time. A stationary mount will be fine.
Having already gained some familiarity with Inmarsat signals, that is one
option. It may very well be beyond my reach, but I would like to educate
myself about what is available on the GOES-13 satellite as well. I even
have a commercial FTA TV LNB to experiment with. It seems like the upcoming
amateur satellites will require familiarity with more gain & higher
frequencies as well, so I have a lot to learn there.
LEO telemetry cubesats and the like are my main interest, but I like the
idea of having a dish to experiment with as well. Certainly appreciate
If satcom topics like Inmarsat & GOES-13 are not of interest on this mailing
list, by all means please feel free to contact me directly if you have any
If you are not using it in a fixed position, but for low earth orbit
tracking on s-band, like I am, I can give more advice. I am using a
1.2 metre dish. In particular the modification for larger feeds,
calibration due to offset feed and real world low earth orbit tracking
