Title: What is this connector for?
Post by: Greekman on June 07, 2018, 12:27:00 AM
I am always in search for RF connectors that are easy to use. So i stumbled on this.

What is the reason the body is two part in comparison to the usual chassis mount SMA connectors?

  i'm guessing it's because it's a bulkhead mount with a center pin that must be crimped. Think of it this way, you crimp the center conductor to the pin. Then you screw the coax with center pin into the barrel which  makes contact with the shield. It's in two parts because the pin does not go beyond the end of the barrel.

  As it is for sale on the 'surplus market' ,the better question is "what WAS it for?" As it obviously is not in commercial use now. It may make a fair mount for a antenna on top of a radio or device.

armymars,
i got what you say, but it still perplexes me there are TWo windows to solder the coax core.

Carl,
you mean using it to attach a wire on the center pin for a DIY whip.
AFAIK on a usual SMA connector there is no way to secure the central pin, which is already tiny to begin with.
NICE way of thinking Carl.

Seems i will be buying one just for experimenting.
