MJW patch feed copper thickness?

Mines 1.6, Still OK? What about double (or single) sided PCB material? FR4 not so good at 2.4? SRBP??
Soldering up tomorrow
BTW, I've found perfect 3mm spacers - 4mm hex nuts (at least the ones I have). Three of them will do a lovely job

Got it all together and soldered it all in one lot with a gas torch and care! Rather than using a bulky compression fitting I put the completed feed in the lathe and took about 0.5mm out of the LNB end of the copper pipe. Then, using a strip of emery cloth, I reduced the external diameter of my LNB. It is now a nice snug 'twist-fit' in the end of the copper. To seat the Rocket internals at the right height I have left the protruding copper at 16mm in front of the patch. Will this be an issue I wonder? - without it being that length, the inner bit will move around at will?? I will design a simple step-up ring for mounting in my LNB holder, pop it on the 3-D printer to make and then trial-fit. Not got a long run from shack to dish so various options on the actual cable I'll use and where I put the amp.
All good fun

PS the stray solder is from where I assembled it earlier, with something that wasn't a N-type and with the patch the wrong way round! Doh!!

I use 3mm backplate to carry a 7/16 socket - no problems with return loss at 25dB

Looking at that Coax, I am worried about the power ratings!

I originally used a POTY as my dummy load to test amplifiers up to 320W output with no problems at all. I just stuck it out of the window for tests! De-sensed all the wifi in the area!
