It's been so long ago that I figured that number, I can't remember how I did 
arrive at it.  I do know I've been using it for years and it seems all of the 
antennas I make are right in there.  Not one complaint from anyone that I've 
sold them to, anyway... It's possible I figured the radials to be 5% longer, 
only made it 2.5% per side.  But that number would be 2878.2 and I probably 
rounded that off to the next higher even number, which just so happens to jog 
my memory when I think of 2808...

I've come up with some wierd numbers like that.  If I don't clear my 
Scientific Calculator, it includes previous calculations into a newer 
calculation.
I can't count how many times I've figured the sides of a triangle and I just 
know that dimension can't be right . . . Clear the calculator and figure it 
again and the new figure is different and looks like it'll fit..
... One who is in peril thinks with their legs.
