VSWR isn't a REAL problem! Deal with it!

VSWR is real and ENGINEERS and Ham Radio operators make

transmission
lines and antennas work; while Physicists wonder if it's real or
uncertain. [My 80 meter antenna has a VSWR of 30:1. It works just

fine!]

=====================================

Anything will work after a fashion. It's no proof of anything.

It is not realised by many amateurs and engineers that the so-called
SWR meter does not measure SWR. It merely indicates whether or not
the transmitter is loaded with its design resistance. Which, of
course, is useful.

The meter not located in the right place to measure SWR on the
feedline. The feedline on which it is imagined SWR is measured does
not exist.

To measure SWR on any line a moving voltmeter is required. SWR is
simply max volts divided by min volts which occur at a distance

apart
of 1/4-wavelength if the line is long enough, and requires no
knowledge of line impedance or its terminating impedances, or of
anything else about the line.

In other words, SWR is just something for Old Wives and "clever"
people to plagiarise and waffle about, on newsgroups and in the
magazines, and so continue to mislead themselves together with the
unfortunate learners, CB-ers, and the novices.

================================

In other words, ENGINEERS make transmission lines and antennas work by
copying what was done last time.

Nothing has changed since Oliver Heaviside, 1875 - 1925.

If anybody mentions G5RV I shall cry.
