[time-nuts] 3 lug triax plug.

[Robert Atkinson]

Hi John,
  Is it actually triaxial or just three lug? I've some small 3 lug coax plugs about 1/2 the size of a BNC. The one's in the link are the same size as a BNC.

  It's a long time since I used a 2801A, but as I recall the connector 
is much smaller than the triaxial one used on the 3478A system voltmeter.
