When you run a 73 ohm "resistor" and a 50 ohm resistor in parallel?

You would need a balun (rf transformer) to match to that antenna ...

Then you would need a suitable name for it. *Let me see, we are mating
up a "dummy load" with a "dipole." *How about "Dummy-Pole?" *grin

I'm glad you called it a 'balun (rf transformer)' instead of a 'balun
(CM Choke)'. Did Cecil review this before you posted it?

That is very disappointing and does not speak well for you.

I certainly expected you to realize a 1:1 balun (1:1 rf transformer
constructed in transmission line mode) IS a common mode choke ... :-(

Hang in there ... you'll get it ... eventually.

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

Makes me wonder if you have been paying attention?; indeed, it has been
the arrl which has been "exposed!" ROFLOL!

'Corse, this WAS from memory, of this antenna-- From some 25 YEARS ago!
When it was first introduced! Hindsight is always better than Foresight!
