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??
