I have a NTN5517 antenna adapter cable with BNC connector:

I tried it with my Astro Sabers (VHF & UHF models) and it doesn't works.
And I have found the reason! The adapter connector simply has no dowel which could press on actuator (antenna switch).
What is the trouble? NTN5517 it is not intended for work with Astro Saber? Then for what it is intended (on the Internet practically there is no information about this adapter cable)?
