[Elecraft] how to optimize end-fed?

[Lynn W. Taylor, WB6UUT]

Maybe I'm missing something, but you have a selection of taps, the 
highest is 16:1.

If the wire is exactly 1/2 wave, then the impedance is going to be very 
high, and the 16:1 tap will come closest to matching a high impedance load.

If the wire is some multiple of 1/4 wave but not a an even multiple (not 
an multiple of a half wave) then the lowest tap is probably best.

I'd disable the tuner and check the SWR on each tap for each band -- if 
I wanted to verify the (very simple) math.
