Hi Peter,

Yes I have some left, I did reply to your previous email with my details for payment. It might be worth checking your junk mail folder.

I have also sent the email again.

Colin,

You made a 3d printed adapter for 22mm copperpipe.
I want to use this LNB after my 10Ghz Eme setup for moonnoise checking.
Therefor I need an SMA connector at the mouth of the LNB.
Do you have experience with that?

You could just use a short length of 22mm pipe with the far end capped and an SMA connector fitted to form a waveguide to coax transition. I don’t have the dimension’s in my head but I am sure someone must have published details somewhere.

I used the info contained in this document, also the G3PHO Modified Feed using copper fittings. It seems to work very well on my 65cm offset dish. http://www.w1ghz.org/QEX/circular_wg.pdf
