You don't care whether all your power is going into a dummy
load or into your antenna?

We are trying to figure out something about transmission lines
so we take away the transmission line and replace it with an
"equivalent circuit" that doesn't act like a transmission at all?
How in the world does that tell us anything about transmission
lines?

Am I getting sucked into the bottomless black hole of transmission lines?
Yea, I care! If I want to test or tune my transmitter or amplifier and need a
dummy, I use dummy load. When I need to radiate killer signals I use my Razor
beams, but they are designed to have 50 ohm impedance and broad bandwidth
(possible, been there, done it) no matching crap, no reflections (ok very
small) and I don't give a Freak about nurturing reflections on the line. I hate
reflected waves and I suppress their generation/reflection/travel and endless
discussions about problem that nobody wants.

Huh? You haven't figured that SWR is bad for transmission lines?
All I want to know about transmission line that it doesn't have impedance
bumps, keeps its impedance, that it has lowest possible loss and doesn't
radiate or let the water in. (That goes for open wire feeders too :-)
Oh, color doesn't matter and it should be repulsive to chipmunks and other SWR
ignorant critters.
Why is this endless argument about reflections going on? We know they are bad,
we know how to eliminate them, so what's the problem? You love them so much
that you want to keep them in your coax?
There are no reflections around this shack, only in the mirror of my ugly face
after 48 hr contest.
OK hit me now that it is impossible to have reflectionless antenna-coax-tx.
My answer, yea, there are some (very little) and they are insignificant to me
to worry about and lose sleep and hours at the keyboard. Ins't it like eunuch
dreaming about sex? :-)

An SWR between 4:1 and 16:1 is what allows me to use a 130 ft.
$20 dipole fed with 400 ohm window line on all HF bands without
needing an antenna tuner. What's wrong with live and let live?
I find your approach to antennas boring as heck but I am not
going to rag on you about it. Different strokes for different
folks. One has to have a transmission line anyway - might as
well let it perform the matching function.

Did I deny to let you live with your SWRed piece of wire? Be happy.

If my 7 el Razor, Quad Yagi log driven design is boring, and your piece of wire
is exciting, may the SWR be with you!

Gee, what a revolutionary concept, let your transmission line do the matching
for your doublet with open wire feeders. Yo everybody, tear down your coax fed
beams, arrays, towers, just put up doublet and work the WAS in no time. Can you
picture all those stupid contesters, serious DXers with decent antennas wasting
their efforts to eliminate SWR from their feedlines? Yep, I can picture trying
to use coax feedlines for matching kilowats to non-resonant antennas. Good for
melting the ice in the gutters.

Be happy with your doublet, I am looking for "boring" killer antennas that can
hear and work stuff that others can't. To me much more fun and challenge than
your SWR endeavors.
