[TowerTalk] loss resistance

[Bob Alexander]

Hi Pete,
Losses and feedpoint Z add so they are effectively in series.  Thats why  we
quite often
see a 1:1 SWR at the base of a vertical over poor ground that has no radials
at all or not
enough radials.  Z should be around 34 ohms (1.4:1) over a perfect
ground.  The ground losses add to it bringing the value closer to 50 ohms.
ADD more
radials and the SWR should go up. (without a matching device at the
feedpoint)

Am I correct in assuming that the loss resistance and the feedpoint
impedance are in parallel at the feedpoint of a vertical?
