[BC] Smallest AM Radiator

[Bailey, Scott]

Peter,
   Top loading....now that is the answer so some of the AM problems of
fighting tower restrictions. I have found that most city/county zoning
officials don't object to anything 100' or less.  This is good for
non-directionals, especially Class C's.
   Now that's the reason why I think there should be a rule making for
Class D's to be able to have the same minimum efficiency as Class C's,
241 mv/m.

Scott

Smallest conforming radiator is probably 45 degrees on a Class C 
frequency, or 60 degrees on a Class C/D frequency.

As the highest Class C frequency is 1490, 45 degrees would be roughly 80

feet.

As the highest Class B/D frequency is 1700, 60 degrees would be roughly 
95 feet.

One could easily add about 20 degrees of top-loading with very little 
additional cost, thereby making 45 degrees into 65 degrees, and 60 
degrees into 80 degrees, respectively.
