[SADXA] CADXA SHARE Vertical antenna

[RSoifer1 at aol.com]

Tom,
 
The club has a number of antenna experts, one of whom I (BSEE, 1963) am  
not.  Nonetheless, it is my understanding that the vertical you  describe will 
exhibit some directivity to the east, but not gain over an  equivalent 
vertical with 48 radials in all directions.  The directivity  results from 
losses to the west.
 
At other frequencies, the patterns will be different but will also favor  
the east.
 
OK guys, have at me.

As an extra class I suppose I should know this but, I can’t say I  
precisely know:
hSuppose I have a 1/4 wave vertical antenna pertup  pretty much in the 
clear of man-made obstacles and I make a set of 24 radials  of about 1/4 
wavelength.  I arrange these radials so that they all occupy  azimuths of 0 degrees 
(north) through 180 degrees (south).  
t
Will this arrangement give the vertical a certain degree of directivity  to 
the east?
 
If the above statement is true, will this be frequency independent?
