I tryed three times to send the sketch. Certainly, Yahoogroups is blocking the
attached sketch, I see.
You have already furnished the distanCe between holes of feedhorn ring
(5.3/4"). Ring deep 1'. OK. tHe opening of the feedhorn extends down 3/4" from
the bottom of the ring. OK.

Hello,
I did not see your sketch. I have uploaded some pictures with
measurements to my webpage:
http://home.nycap.rr.com/simard/
I have to assemble to dish to get the other measurements. I should
have those in a day or 2.
The feedhorn ring is 6 1/2" wide
The holes ( on center ) are 3/8 " in from the outer edge of the ring.
This makes the distance from center of hole to oposite hole 5 3/4"
The ring is 1" deep
The opening of the feedhorn extends down 3/4" from the bottom of the
ring. ( see pictures )
The original supports were like the one pictured. It was a round
tube that was flattened on each end and had a hole drilled through it.
The original tabs were about 2 or 3 inches long. The most important
measurements are for the length from the dish edge to the ring edge.
The original supports had a slot where the bolts attached that gave
about 2 inches of "play" on both ends for fine tunning.
As well, the feedhorn has allen screws that allow you to adjust the
ring from flush to about 3 inches below the bottom of the outter ring
for tunning.
I will get the bolts needed to assemble the dish and once I have that
assembled I will give you the measurements of the dish itself.
Thanks a lot.
Bill
