[Elecraft] K2 KAT100 and BL2 questions

[Brian Lloyd]

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.
