CM Adding the insulation increased the feedpoint impedance from
CM 57 ohms to 65 ohms which means the forward and reflected
CM waves on the standing-wave antenna were attenuated more
CM using insulated wire and sure enough, using that particular
CM insulation reduced the EZNEC maximum gain by 0.12 dB.

CM Many people have noticed shifts in resonant frequency when
CM their antenna gets wet. Water has a dielectric constant
CM around 80.


Speaking of odd antennas, how about using a long neon tube as an
antenna and what would eznec give as values then? After all a plasma
behaves like a conductor doesn't it?
