I’m building a qfh for a 4’ dish. I tried a helical but the dish is too deep for it to illuminate. I need the qfh to be LHCP. I made a scaffolding for the frequency I need and 3d printed it. I ran my wires, but here is where my confusion sets in.. which short and long legs need to be soldered together and where does my center pin and my shield need to be soldered? I’ve asked Google, Grok, and Claude and all 3 of them are giving me different answers. The wires meet at the top of the scaffolding where the pigtail will be soldered. I need the top to fire towards the dish.

Anyone have experience with this that can give me the correct answer? Any help would be greatly appreciated!

I acquired several of these connectors over the weekend at an estate sale. They are N male to N female, but there’s one unique thing I’ve never seen. The halves thread together and the female side isn’t just a barrel connector; it’s got a solid center conductor that slides into the male side. There’s a locking ring on the outer part that makes it look like it’s tunable to optimize SWR. Is this a common connector? Anyone know what the part number is? I’ve never seen these before.

Thanks in advance!
