For kicks, cut it open. I did this once with a right angle "N"
adapter that I bought at a swapmeet, and in which I observed poor
performance. Inside I found the center conductor was a small
spring! The idea, I believe, was that the spring would naturally
form a gentle circular arc from the center pin of one connector to
the center pin of the other, maintaining nice spacing from the
sidewals. This would be fine at DC, or maybe HF, but at UHF this was
worthless. The spring was electrically a coil, in other words an
inductor, which was altogether the wrong thing. Laughable.
