[Elecraft] The use of a doublet

[Wes Stewart]

This is simply untrue on all counts. Is wire size
unimportant in AC power circuits?  Of
course not.  Larger wire simply has
lower resistive loss.  Ohm’s law is
still in effect at radio frequency.  And
for a given size, as the frequency increases, the resistance increases due to
skin effect.  So wire size can be more
important at h-f.

 

Also, assuming that the dielectric is mostly air,
polyethylene or something comparable, the loss due to the dielectric is
immaterial for all practical purposes.

since the energy flow is between the wires not in them.  The insulation is 
of more importance.  You might want something stronger for mechanical 
reasons.
