Does anyone know if the KAT100 has enough range to match a radiator
that is close to (or is) an end-fed 1/2 wave? What I am thinking about
is feeding a dipole at twice its resonant frequency so that it is
effectively two end-fed 1/2 wave sections and then feeding with
ladder line. Now the ladder line will probably act as a transformer to
change the matching equation. (I know it won't change the SWR but the
magnitude of the resistance and reactance components will change.)
This also brings up a question I asked much earlier but didn't get a
good answer to. Will the Elecraft BL2 4:1 balun intended for 300/75
ohm operation still work properly when feeding the equivalent of two
end-fed half-wave antennas? If I recall these would represent about an
8000 ohm impedance. I was thinking of locating the balun very near the
tuner and using window line to the doublet. I am concerned about
losses and arcing (100W) in the balun in that specific instance.
