Pro tip: spent $80 on that fancy crimp tool for D-sub pins and it was a lifesaver
Was fighting with a cheap ratcheting crimper for months on a 737 nav antenna harness till I grabbed a real M22520 style one. Anyone else drop money on a tool that actually paid for itself quick?

Yeah totally feel you on that. I fought with a cheap ratcheting one for a year on a 767 antenna install. Finally dropped the cash on a real M22520 and it saved my ass big time. The difference is night and day, no more crushed pins or bad crimps that have you chasing ghost faults. That tool paid for itself after the first few connectors I didn't have to redo.

Yeah "chasing ghost faults" really hits home. That's a perfect way to describe what you get with a bad crimp on a nav antenna - half the time the radio just drops signal for no reason and you're swapping LRUs and checking grounds for 3 hours. I remember that feeling of relief when I finally got the M22520 and crushed my first pin perfectly. It was like the heavens parted and a chorus of angels sang "that's $80 well spent." My wallet still hasn't forgiven me but my blood pressure sure has.
