[Elecraft] Home made Sigma-GT5 & KRC2 or SGC?

[Darrell Bellerive]

I know that this has been discussed before on the mailing list, but no
matter how well designed a balun is, I just don't believe that it will
be very efficient when used with a non-resonant doublet for multiband
operation from 160 to 10 meters. Add a long length of coax and the
losses further increase. The balun must be on the transmitter side of
the tuner for the lowest losses, hence the need for a remote tuner, or a
QTH where open wire feeder can be used.
