Was an outfit here in the U.S actually "Marketed" such!
With claims that would give less than 3:1 SWR, on any frequency!
Wondered how it could do that and still perform- asked buddy (engineer)
and this was the "Black Box" he came up with! (50 ohm, 200 watt, non
inductive resistor! No majic involved, just a Dummy Load, in parallel
with a couple pieces of wire! Think ARRL, finally exposed it!
Yes it will radiate, but at WHAT effeciency?? Jim NN7K

Has anyone ever tried putting a dipole antenna up with the center insulator
being a high power 50 ohm dummy load,then connecting the dipole elements
across the dummy load.This would always keep a suitable match at 50 ohms
and satisfy the transceiver.Would most of the power go to the dummy load and
not the elements and wouldn't radiate.In thinking about this it all
logically makes sense the load would really never change or would it have
some reactance with the dipole elements.
