There have been a few iterations along the way but here is some info on the X band stuff that I'm using.
The feeds are based on 28mm plumbing for 8.4GHz and 35mm for 7.5GHz. Whilst the 28mm works at 7GHz, it is a bit close to cut off for my liking. I started off with squashed pipe polarisers but switched to a more professional one for DSN from uhf-satcom. The LNA is a single CE3512K2-C1 GaAsFET...
