[Elecraft] Off-Topic: Your advice/suggestion about antenna

[David Gilbert]

That is certainly a perfectly viable antenna and probably a fine choice 
for your needs ... but it does not "far outperform" either a dipole or 
especially a 2 element yagi at the same height. (although the yagi would 
of course be unidirectional).  4.7 dbi is dipole territory.  You could 
have gotten pretty much the same result with an E-W 80m dipole and a N-S 
40m dipole fed at the same point (orthogonal fan dipole).  And assuming 
you used capacitors for the EDZ, dipoles are easier to build.
