[TowerTalk] Wire size for 800 meter long wire

[K4SAV]

OK, I guess I have to eat crow again.  My simulation of this antenna had 
an unintended load in it, due to using an old model file, which I didn't 
inspect closely.

This is a pretty good antenna.  On 160 meters, it looks like the maximum 
lobe, off the end of the wire, is around 5 dB at about 20 degrees 
elevation, and it still has 0 dB gain down at 2 degrees.  At 10 degrees 
elevation, gain is generally around 0 to 2.5 dB, almost omnidirectional 
with only 4 small nulls going down to -7 dB.  The suprising part is that 
most of the radiation is from a vertical component, not a horizontal 
one.  There are also a bunch of high angle lobes.  These range 5 to 7 
dB.  These numbers may not be exactly correct because the feedpoint may 
not be as I assumed and the wire may not be the same size.
