Default 20m "ringo"

Hi Jimmie,

What was meant was that the mast inappropriately became part of the
radiator due to the design of the Ringo (which has had a reputation
for being a dummy load). The problem with half-wave designs is they
are high Z. Being high Z they are difficult to choke. Being
difficult to choke, they appropriate masts, supports, feed lines, as
additional radiation surfaces. When you add these lengths to the
radiator (and they are co-linear) then your radiation lobes begin to
climb into the sky (no one there to hear you) and the antenna becomes
deaf and dumb.
