I seem to have been seeing a lot about the technology of the twin-lead

I might learn.

The "twin-lead tuning technology" is based on the laws of
physics, not the approval of the gurus on this newsgroup.


I am not in a position to argue with either side on the issue. I am
just doing my best to learn. Here is one lesson I learned in 25 years
of ham radio, Either there is sufficient propagation for your station
or there is not. Without propagation, a kw amp in a 12 element beam
will not get you across the ocean, and if there is sufficient
propagation, one can make a contact with a dummy load (I saw this
demonstrated once on 75 meters).

Probably the things I remember most about antennas is what I learned
from the two Jims of Taylor Radio, a local antenna MFG company at the
time. "More technological advancements have been made in marketing
departments than in Research and Development."

I realize that there are several here who actively disagree and
discuss their disagreements with each other. I haven't seen any, so
far, that are all BS and have no knowledge to offer. I don't
criticize anyone, but I will ask, suggest, and offer opinions that I
hope will be either corrected or supported appropriately.

I have used experimental antennas that theoretically won't 'work' and
made contacts. One was a roll of 500 foot of wire. I unrolled an
estimated 1/4 wave of wire for 80 meters, on the first try it was
1.5:1 or less and I used it to check into the GA SSB net. I had a
weak signal, but it worked. I also hung an inverted V with a random
length of wire from each side (I don't remember the length, but they
were both the same length.) I connected one side of the feedline and
dipole to the left side of a 100ohm resistor and the other side of the
feedline and dipole to the other side of the resistor. My theory was
that the antenna would be a parallel circuit leaving the impedance
below 100 ohms. I don't know if my theory worked, but I did make
contacts. When I took down the antenna and replaced it with a shorter
dipole, I had a much better receiver than I had with the resistor.

I am always looking for that 'best' all-band hf antenna so I don't
have to change or tune, etc. One day I'll either find it or die
trying. Until then, I plan to enjoy learning more about antennas and
experimenting with them.
