Hi, Tim;
We still make the S/L patch feeds and may bring back the tribander, if there's enough demand. We also still produce the 1.2m and 1.8m dish kits and now have a 2.4m kit in the works. It's been the UAV industry that's kept us alive since the failure of AO-40, so our products are now made from aircraft grade aluminum and are milspec Class II gold anodized.

I am not sure Tek Sharp continues to make the patch feeds. They certainly do not make the tri-band feed, but I was able to get a dual band patch from them in June 2009 for one of their hardware cloth dishes.

Bob, Regarding your Cu wire dish... you might look at the Tek Sharp dishes as an easier alternative to "rolling your own." I picked one up on ebay about a year ago and put it in my attic... waiting for amsat-dl :-)

Drew, I have a spare PF dish about 60 cm, but it is steel, not aluminum like the
G3RUH. I used it on AO-40 for 24 GHz. Let me know off-list if you want it.

---- previous message ---- You probably have one of the K5GNA "BBQ" dishes. The G3RUH is a solid round spun dish.

I'm looking for one of the 60cm G3RUH dishes
Got one, (but not available).
Questions: I measured reflector grid separation as .88 inches which works out to be about 0.18 wavelength. I always thought the grid had to be tighter than 0.1 inches to be an effective "surface".
Maybe the difference with almost double the spacing is not that significant? (especially for a steel one which would be quite heavy.
Reason I am asking is that I also need another S band dish (at 70 MPH on the roof of a tracking van) and we are thinking about building one by using an old solid 6' TVRO dish as a form and laying in copper wire and soldering it to copper straps. With all that labor, I'd not want to get the spacing wrong.
Bob, Wb4APR
