[TowerTalk] Bazooka antenna

[David Gilbert]

a.  So publicly advocating against the use of fan dipoles is not a 
"crusade" of sorts?

b.  You think bad key clicks and SSB splatter 3 db down aren't at least 
as easy to detect as a harmonic 30 db down?

c.  You think key clicks and SSB splatter aren't a far more pervasive 
problem than interference from harmonics?

We must be living in different realities with some sort of planar 
junction at this reflector.
