Help with identifying this

[TonyV225]

Ok Ive had this forever and asked at one other time but now have a pic WHAT THE HELL IS THIS?? Im thinking a SWR matcher in this barrel end?? Theres a removable cap you can see then theres an adjustment set screw under the cap. I guess I can just test it if nobody here has a clue. Ive never seen one of these anywhere else or again otherthan this one that Ive aquired back in the mid 1990s.

Kinda looks like a Lightning Arrestor

No I have lightning arrestors this metal cap comes off and theres a set screw down in the hole. It was made by vectronics

It looks like some sort of thruline device or field measuring jumper, for a scope perhaps.

Damn I was really hoping someone here out of all these people would have know what this is forsure but Ill have to experiment with it Im guessing its a matching network for SWR. must be a hard to find

Take it apart and let's see what is inside!

An attachment for lightning protection OR a means to hook up test gear inline?
???

I bet it's just a ferrite core and the set screw holds it on.
