Quick question for my european folks, how can I get a "Prime Focus" dish of at least 120cm of diameter ?
Impossible to get my hands on one !!
This is for QO-100 of course.

Today, i was working on my 2,6 GHz Power Amplifier.
I replace the input circulator with a little piece of coax and replace the output circulator with a piece of PCB to elevate another piece of coax with greater diameter for high output power, the PCB is for ground purposes too.
I try my best to modify this bad boy, first time for me.
If you have some idea, keep me in touch ! πŸ‘πŸ€˜πŸ”ŠπŸ“ΊπŸ“‘πŸ“»πŸ˜Ž

The input connector was removed and replaced with SMA connector, perfect for the amplifier cover.
RF Isolator and output connector removed and soon replaced by a small piece of coax and another connector. πŸ‘
Which connector can i use on the PCB directly ? πŸ§πŸ€”

Est-ce que certains d'entre vous ont des conseils pour dΓ©buter en ? Ou de la documentation (si possible en franΓ§ais πŸ˜‡). Je suis perdu entre toutes les normes, matΓ©riels et logiciels.
