[TowerTalk] Is Amphenol TWB 4001 equivalent to LMR-400?

[David Kozinn, K2DBK]

A friend picked up some unused Amphenol TWB 4001 which his employer was
discarding.  I've been trying to find out definitively if this is equivalent
to LMR-400 electrically. I've found some data sheets for parts that seem to
indicate that physically it can use the same connectors as 9913 or LMR 400,
but I wanted to know if it's electrically similar. Can anyone help with
this?
