I gave up on using ground for anything other than ground rods and lightning
protection. For antennas where only one connection radiates to significant
degree I refer to a current sink as the device one uses to accept the current
from the opposite side of the feedline. This allows me to

B, A and GND, B and GND or well you get the idea.
Any apparent benefit you get from using anything other than A and B

Nope! It has NO relationship with the earth, nor is one needed. This
use of the word ground is an ongoing source of confusion and
misunderstandings. Hams to go extremes to install ground rods,
Jim, IMX it's a mistake to equate RF ground with an Earth connection.
An RF ground is just a low-impedance, low-reactance current sink for RF.
Of course it is an integral part of the antenna circuit.
An RF ground would not be expected to radiate, and most counterpoise or
radial setups don't

Ron,
I have been preaching similar points in ham circles for years now - and
I find that many hams cannot visualize the difference between a
ground (meaning a return path for current) and Mother Earth.
Actually any point where the RF current crosses the zero voltage point
is a point of RF

Matt,
Many years ago, I had an EE professor who said it right - there are two
disciplines in EE that need to consider 4 dimensions - the 3 dimensions
of space as well as that position in time. One is 3 phase motor
analysis and the other is analysis of an RF wave in space (or on
antennas). I
Is there a way to connect a long wire to a BL-2?
I vaguely remember seeing a post re: this kind of setup used as a way to get
a wider range of matches without using a longer wire antenna.
My rig is a KX1 and where I am going to be backpacking makes it impractical
to use a balanced line
Why not connect the wire directly to the KX-1 output? The KXAT1 will
handle a pretty wide range of load impedances.

I agree with Bob. The KX1 does very well with nothing in between it and an
end fed wire.
The most important thing is to have an RF ground at the rig - especially
when using a wire that's 1/4 wavelength or less long as we often must do
when travelling light.
For my KX1 I carry two 33 foot
