[TowerTalk] What coax is this?

[Grant Saviers]

I think unless it has MIL markings the varieties are endless of what 
many call RG142 or RG400.  The MIL17 stuff should be silver plated CCS 
solid and stranded respectively center and braid.  However, I have both 
single and double braid silver plated RG142, the single not marked MIL.

Then for RG316 subminature I have extruded TFE clear light brown and 
white TFE tape wrapped insulation.  The former marked MIL17 the latter 
RG316/U MOD.  One more example of variety in the surplus market where 
these came from, although the MIL stuff was from a DOD contractor surplus.

And then some CB coax that is clear jacket over bare braid.  Not TFE.

Caveat emptor for ebay coax.
