This gives a 90 degree phase shift.

As Mike mentioned, one of the sample models is "Vhfgp.ez". Take a look at the
source placement in that one and you'll see there is no break between the
vertical and the (sloped) radials. Or take a look at sample "Bydipole.ez".
Again, no physical break in the wire.

loaded with ice every winter, I've never noticed this wire stretching in
4 years of use. Takes full power easily.
3) I have no experience with a Spiderbeam.
4) My Inverted L is fed direct from 50-ohm 7/8 hardline - no matching
network whatsoever. 1:3 minimum SWR at resonance.

around 1813 kHz (that's OK with me) but the SWR is 1.9:1 minimum,
which my Yaesu Quadra amplifier does

Sad news.

Richard Fry, you know anything about this? A 5:1 change in soil seems way
out of line with what I recall from fields at WSPD on 1370 kHz and WOHO on
1470 kHz. Were those stations exceptions?
I don't know about further out where you'd have to proof an AM station
but I just ran some models and
Four elevated radials had less than 40 ohms feed resistance. About a dozen
buried radials had around 60 ohms base resistance.
Field strength was identical despite the resistance difference with the same
length resonant radiator.
Is it right that this was with radials significantly longer
