a bit high. I checked the Radian site and sure enough that is  what is 
listed.  So I drug out my old Peoria Rohn Catalog, circa 1983 and  researched 
dimensions. Peoria Rohn specs call for a 2' X 2' by 4' deep  hole for the tower 
that Bob, AD5VJ is installing. It calls for guy anchors of  2' X 2' by 1' 

Which raises the question: Did Radian re-engineer  the base dimensions or did 
the fear of litigation cause Radian to up the  numbers?

    In 1983 there wasn't a tower standard - now there  is - the TIA-222-G 
Structural Standard for Antenna Supporting Structures and  Antennas. You can 
a copy of it - it ain't cheap at $380.00. 
    Every time a revision comes out, tower  manufacturers change things to 
meet the new  standards. 

As an aside, this standard is  for steel towers. Aluminum towers ARE NOT 
covered and don't meet any of the  specs.
