SO-239 hood?

[Alex Fraser]

First of all "UHF female crimp connectors" sounds oddly exciting, even 
at my age.

Wandering back to the point I have seen those in my searches and will 
probably buy a couple to see what they look like.   Does crimping hold 
up well outside?

I have a metal lathe and I'm comfortable with making threads. The outer 
body of a So-239 would be easy, but that inner part the the center pin 
fits into would be trick to make. Also the crimp they use to hold in the 
insulating material could be a problem.  I don't have any test gear, not 
the skill to figure out the electrical qualities of these connectors.  I 
seem to remember seeing the specs for teflon vs bakelite somewhere.  So 
often the electrical specs just aren't given. My application in this 
case is HF and I'm sure the old UHF connectors are adequate.  I can 
almost here the "tsk. tsk, tsk" of more serious hams wondering why I 
don't use N connectors...
