Default Standing-Wave Current vs Traveling-Wave Current

On the contrary, I just whipped out an EZNEC rhombic
without taking any special care. I copied it out of
The ARRL Antenna Book, 20th edition, page 13-13.
I only installed ten zero ohm loads, but clicking
on "Load Dat" clearly shows the phase shift in the
traveling wave current along the wire.

Sorry, a rhombic won't run on the free demo version
of EZNEC.

This is just too, too easy! :-)

Too bad for you the threaded newsreader shows that
the only thing I wrong above was "clearly shows".
It also shows that you wrote the rest. Any idiot
can falsify a posting.

Well, are the standing waves falsified? This is a "traveling wave"
antenna, is it not? Presumably any idiot can figure that one out.
This, of course, has already been answered by me in another posting.
Perhaps you want to look under the bed for idiots there too. ;-)

I don't mind being called an idiot, it elevates me in this thread!

I've just discovered that this "copy" from the ARRL
The ARRL Antenna Book, 20th edition, page 13-13.

must be quite a departure from reality. In outer space?

Well, I trust Cecil hasn't mislaid his glasses once again, performed
another math error, or tried to use his car keys to get into the
house; but when we substitute his former 1/200th wavelength above
ground, this antenna clearly exhibits a SWR of 1.33.

Of course, it can be jimmied back into outer space in an effort to
suppress evidence of standing waves, but like the Ghost of Christmas
Past, those chains will still rattle poor ol' Cec'. (Will he give
Cratchit the day off?)

Cecil's clever crafting can always be mined for simple problems. Pay
dirt every time.

Now that I have been exposed for what I am, I can full well expect a
lump of coal the size of West Virginia in my stocking. I'm going to
need a larger mantle. :-(
