SG-m507 brings the smaller one alone, which I think will a better option to save some money IF the part is around the measurement what we are looking for. They are selling them locally, so I will try to take a look personally next week.

In the interest of giving ourselves more options outside of fully assembled antenna springs, I thought it would be useful to figure out what the cone piece itself is called.
I've seen them referred to as "whip adaptor" and "ferrule", which should give us a decent place to start to find one with the right proportions and setscrew location.
