[BC] Skirt feeds.....

[Dave Dybas]

I've had pretty good results modelling folded mono-pole towers by following this:
 
If a skirted mono-pole is modelled in NEC there are a few tweaks necessary to obtain valid results.
 
A) The skirt wires should not be tied together at the bottom...in the model.
 
B) Each skirt wire should be excited by its own source.
 
C) All sources should be the same value
 
D) The actual base impedance is the value of one of the skirt wires divided by the # of skirt wires.
I'm certainly no expert on the subject of NEC or folded-mono-poles but after a little research and hours of computer modelling, I think I've got a better grasp of how to do it.
