1/4 wavelength away from that very high impedance
is a very low impedance.
Ah yes indeed Cecil. BUT what is the impeadance at the ATU at the
frequency you are using, for a given length of random wire?
A lot of house lots or "sections" (as we call them here in NZ) these
days tend to give you about 60 Ft/20 metres in the clear and that gives
you a Really high impeadance when end fed on 7 Mhz!!!
A good old centre fed ladder feeder is so much more controllable and
less lossy, that's why I'm a Z match fan too.
