Polar Mount for a 1.8 meter Prodelin Offset Antenna

[mikekohl]

Just went through some old pictures circa 2010, and found a mechanical drawing of a commercially manufactured heavy duty polar mount once made and sold by Prodelin,
for their 1.8 meter offset Ku-band antenna. They quit offering these more than a decade ago, but if anyone has an offset dish of this type, the drawing below could serve as
a template on how it should be done. A huge job for a fabricator, but thought that creative minds on this forum might find it useful.

I have in storage a 1.2 m, heavy-duty, TX-rated Prodelin with the standard AzEl mount and reflector heater. I gave away the equivalent 1.8 m version. The 1.2's mount hardware is a beast; the 1.8 is worse! I declined when one of my clients offered me a salvaged 2.4 m version. A 10' or 12' mesh would be easier to put into service for the effort!

Two years ago, I conferred with a colleague/supplier near L.A. about the availability of a polar mount for the 1.8. The answer was "there is a custom part available if you know where to look. I don't think you'll be interested as my basic cost to bring it in is over $8000!". Yikes.

If someone reminds me in the spring after the snow melts, I could take some photos and dimensions off the 1.2 AzEl for a set of reference points.

Very interesting. I have 3 of those dishes. Thanks for sharing.

I have one of those mounts, never used it. Been in my basement for 6 years. It is massive, believe it uses a 5 inch pipe.

To make clear it is a polar mount, all it needs is a actuator and a controller and of course a 1.8 dish.
