Ok fine, still have to figure out how to keep it steady.

Depends on your LNB mount etc. I took 115mm , that works well with Triax dishes and apperantly also with other dishes.
I’m also using Triax offset 100/110 in my balcony. Here is a photo of the patch soldering.
I don't see any solder ? ; -)

I discovered that standard M4 nuts are 3.0mm thick. When soldering the top of the patch plate, I put some between it and the bottom plate to keep the distance OK. After soldering you can simply remove the (loose) nuts.

Hacksaw is one possibility, another approach is what PE1CKK did: http://www.hybridpretender.nl/, middle of page.
Perhaps easier to make weather-proof.
Another hint: you are using the plastic TRIAX LNB mount, but I found that POTY+enclosure+LNB (on longer arm, hence heavier) puts strength on the plastic bracket. Triax also sells an aluminium bracket, if you find that the strain causes things to sag perhaps that's a possibility.

No need to be weather proof, as my dish setup is in balcony under the roof and behind window.
Is the yellow mating piece electrically conductive? It should be otherwise you lose quite some signal.. there has to be currents flowing in the walls of the waveguide..
Yellow part is plastic. Lnb tube and Poty tube are end to end, as Lnb tube is 0,2mm too big to fit in Poty tube.
