Hi Gang,

I recently re-kindled my interest in satellite operating ( thanks to 
Lyle KK7P for the inspiration ) and I'm going to jump in with both feet 
on AO-40. I've decided to use a DEM 60 cm dish, and I plan to homebrew 
a K3TZ patch feed. My question for the folks with this type of patch 
relates to the nylon spacers. K3TZ says on one of his pages to omit the 
spacers because they degrade the performance of the antenna. How is 
everyone maintaining the patch spacing? I  thought about using a slab 
of teflon or delrin (of the correct thickness) epoxied between the 
patch and the reflector. I'm assuming it's the screws through the patch 
and reflector that hose things up.

Any input from this august body is appreciated ;^)

73,

John AA2BN
