The f connection is similar to the Smart Titanium single LNB. The Vision tool is useful for getting it on and also for pushing f connectors onto the cable. No more sore fingers. I find putting most of the self amalgamating tape on first then screwing it in then putting a few inches on the top bit over the nut makes the process slightly easier
but it is still very fiddly due to the lip.
I fired up the Comag to see what quality 11046H was on the LH 1m using a Black Ultra LNB in prime focus so its better than your offset. Its fairly strong here at 27% which means it might go off briefly in torrential rain. I would expect similar on an 80cm with a reasonable rain margin.
I suspect your Black Ultra is locking it perfectly well so it's a bit worrying that you are getting no lock on the Red Rocket.
Or maybe the laid down gauntlet will have to be picked up. The body of the Opticum Quad seems quite slim so it would be fine for most multi-LNB uses where the cap is not too big.

I wonder if it turns out to be a good performer like the Smart Titanium Quad but not quite touching the Black Ultra.
What ever you get it will be as interesting as ever.
Thanks for the close up of the lighthouse.
It looks very impressive. The ink stamp gives it character. I can't help thinking I saw it in an old film
The Riddle of the Sands which was on a few years ago but it might just be my dodgy memory.
