[Antennas] Info on RG400 coax

Sat, 24 Jan 2004 07:39:14 -0800

Curly,

RG-400 cable is identical to RG-142 cable, except for the center
conductor.  RG-142 has a solid steel center conductor that is copper
plated and silver clad, while RG-400 has a stranded copper center
conductor that is silver clad.  Everything else is the same:  Double
silver-clad copper braid shields, PTFE dielectric, and translucent brown
jacket.  Obviously, the RG-400 cable is far superior to RG-142 where
flexibility is needed.

The current military specification for RG-400 cable is MIL-C-17/128B,
and its designation is M17/128-RG400.  It is nominal 50 ohm impedance,
and the VOP is nominally 69.5%
