"Looks like the general concensuss is to keep this one in service and not even bother trying the Diamond antenna."
The Diamond is not even in the same class as this antenna in terms of construction and quality. There is a reason this antenna's list price was in the $500 range and the Diamond is little more than $100. I agree with the other poster, don't drill. The radials mounted about an inch down from the top of the aluminum part, not at the bottom where the "N" connector is. Get yourself some 1/2 inch wide, 0.100 soft aluminum (that's what they used on mine) and bend in three pieces to make the radials. Maybe one of the others who is a better draftsman than I will make a sketch for you. They are held onto the base by three (probably #8) machine screws in clamp fashion. This antenna is well worth the effort to get it going. Good Luck.
