[Elecraft] Using "Buddi Pole" Deluxe Antenna with K3

[Bob McGraw - K4TAX]

I agree with Tom on this.  My simple solution is a length of wire, center 
fed with light weight TV 300 ohm line which is terminated into a 1:1 current 
balun at the radio.  Put it up in any fashion, any height and enjoy 
everything from 160M - 6M as long as the internal tuner will handle the 
task.  It will work very efficiently on any frequency where the length is 
1/2 wave or more and with some compromise on those frequencies where it is 
less than 1/2 wavelength.  Overall the costs is less than $50 and can be 
packed and transported very easily.  From experience it makes no difference 
if it is 5 ft above ground tied between bushes or at 50 ft.  The performance 
and enjoyment is the same.  And it is certainly much less problematic than 
those that use coils and mechanical parts and lighter weight too.
