[K3CAL] Help with an antenna project

I figure that antenna to be much like a flag pole. 
So I googled "how much concrete for a flag pole" 

And came up with this 

http://www.admiralflagpoles.com/resources_instructions_residential_flag_poles.htm

Looks to me a 30 foot pole needs a hole 36 inches deep and 24 inches in diameter

Here is a link to sakrrete (the concrete in the bag folks) website with lots of calculators on it

 Good Morning,
 
 Thank you for an enjoyable
 field day experience.  Between the good 
 friends, good foods and good contesting, it was
 an enjoyable weekend.
 
 Getting back to ham radio, I am putting up a
 Cushcraft R9 at the home 
 QTH.  I plan to
 put the R9 on top of roughly 12 foot high mast with a 
 concrete base.  After checking the web, the
 ARRL website and the 
 instructions that came
 with the antenna, I still can not find any 
 information on how large to make the concrete
 base.  Because of where 
 the antenna will
 be placed, I am not expecting to guy it.  The location 
 is fairly well shielded from high cross
 winds.  However, if need be I 
 will add a
 horizontal support off of a balcony that is about 20 feet
 
 above grade.
 
 If anyone has any thoughts on the size of the
 concrete base or can 
 direct me to where I
 can get information on how large it should be, it 
 would be appreciated.
 
 73s,
