This suggestion by K4OJ works very well. Thanks, Jim.
I bought 1/2" (ID) copper pipe and cut a slot in a 2.5" piece with an
inexpensive metal cutting abrasive blade on my table saw. (I find these
blades very useful for antenna work.) After removing the burrs,
this slips over the end of a 5/8" ground rod which is actually 9/16". The
Polyphaser clamp fits this very neatly. A little Polyphaser copper grease
on the pieces gives me peace of mind. The entire arrangement goes together
like it was designed this way.
Thanks fellows for all your help.
