Greetings,
I have come by a Singer Stoddart 94592-1 rod antenna coupler. It is a
cube about 4.5" is green and has a telescoping antenna on top affixed
by a screw on BNC type connector. The output is BNC and there are two
binding posts for B+ input I believe. I haven't been able to find a
thing on the www about this device, although, i did see one listed on
ebay once for big bucks. Does anyone have any info on this device
they would share with me? The device is for H.F.

An EM specialist may shed more light on this subject.
Twenty years ago, when I managed an EM lab among other responsibilities,
Singer Stoddart was the #1 supplier of laboratory quality EM measuring
devices. They designed and sold EM test instruments including receivers,
antennas, couplers, that were traceable to NBS primary standards.
I suspect you have a very expensive coupler for a receiving dipole for
measuring radiated EM noise fields.
[For about $40,000 you may find a Singer Stoddart receiver and antenna
set to use with it g].
Any professional EMers out there??
As I read my earlier post, it comes to mind that the matching receiver
was an NM-40A ... quite expensive in the mid 80s.
