[Milsurplus] UNIVAC Antenna Coupler

[David Box]

I have what I believe to be a Univac or ERA Antenna Coupler that I would 
like to find out information on before I just tear into it.  I have no 
idea if this unit has any significance so before I go messing with it am 
trying to find as much information as I can.  My intention is to try and 
use it for remote matching of long wire vertical assuming the interface 
is workable.

There is a DD Form 1574 tag attached stating the unit is serviceable and 
has 5821-00-927-0416  7010340  Univac Coupler written in the block for 
FSN, Part NO and Item Description.  There are no plates or markings on 
the unit itself, they were removed.

Connectors are a C for RF with XMTR 1A5J1designation and a Control 
Connector that is 20 pin male hermetic round course thread with 1A9J5 
marked on unit.

The only other markings are on the cover that appears to be the control 
end  "Caution  Remove Cover and Unsolder RF Connector to Network Before 
Detaching Discriminator."

Any information or pointers as to where I can get any information would 
be appreciated.  I did find http://vipclubmn.org/couplers.aspx web page 
and the units depicted there are very similar with the exception that 
the mounting feet on this unit are rotated 90 degrees with respect to 
the control end (left on the photos).

Thanks for any help.
