.. Let's put that into context. For a 12' vertical radiator operating on
160M, you have a 4/160th's wavelength radiator. Radiation resistance
is running on the order of 1/4th Ohm. If you manage to hold all Ohmic
resistance to that value, or lower (everywhere - in TOTAL) then you
verge on 50% efficiency, or better.


And ground losses are likely to be in the neighborhood of ten ohms
or about 2.5% efficiency.
