[TowerTalk] Rai beam

[WA4TUF@aol.com]

I am suspicious of all the "gain" claims too.  Elmer once told me to forget 
about gain - the real value of a directional antenna is the front to back and 
front to side attenuation.    The theory is that reducing noise and QRM by 20 
db or more in three out of four directions means you can hear (and therefore 
work) weaker signals.  To that extent, even a rotatable dipole will be better 
than a vertical (forgetting take off angle for the moment).

That makes sense to me.  
  
Is Elmer right?
