The CIA W.M.D. department must have told you that naughty fib.

The SWR on your 380-ohm transmission line to the antenna is umpteen
times greater than that!

Isn't it time you changed the name of your SWR meter?

I'm not talking about SWR on the series section transformer,
Reg, I'm talking about on the 50 feet of RG-213. And it's
not "umpteen times", rather limited to about ten times.

Nope, for a G5RV with the nominal 70 feet of 50 ohm coax,
the SWR meter is indeed reading the SWR on the coax.
Remember, I'm not using a tuner. The coax from the G5RV
goes directly to the transceiver through the SWR meter.
I actually use my SWR meter to display the SWR.

I see you are happy to change names when in a tight corner.

The name "Transmission line" has been conveniently changed to "Series
Section Transformer".

But it still has standing waves on it far higher than what you claim
for all bands. And don't standing waves increase loss on SST's just as
much as they do on transmission lines?

Louis is turning over in his grave - yet again.

But what the heck? A G5RV will work even if you havn't got one.

I once set up an 80 feet dipole without a series section transformer.
Unsurprisingly - it worked. ;o)

As you know, standing waves increase loss on SST's just as much
as they do on transmission lines *OF THE SAME LENGTH*. For instance,
on 3.8 MHz, that 300 ohm series section transformer on a G5RV has
an SWR of about 20:1 and a line loss of about 0.7 dB, about 12% of
one S-unit. That's a small price to pay for multi-band operation.
And using Wireman #554 (like I do) instead of 300 ohm twinlead will
cut those SST losses down to 0.37 dB, about 6% of an S-unit.

If you fed it with ladder-line, you fed it with a long series
section transformer. :-)

.. . . . and your SWR meter is not an SWR meter - it is a transmitter
loading indicator. ;o)

Go on then - call me a copy cat!
