I considered using a ring of copper tubing with all the radials
soldered or securely fastened to it ... but threw that out when it
dawned on me that the ring served no real purpose except to 'look good'.
My solution was simple: take 4 or 5 radial wires, crimp and solder
them in o-ring type solder lugs ... and then take all those lugs
together on a small bolt of the correct size, tightening it with a
lockwasher and nut.
An extra 0-ring lug in the stack has a #12 THHN wire going to the
ground rod and 'ground side' of the SO-239 mounted at the base of the
You can see the feedpoint (sans radials) on qrz.com (at the very
bottom of the page)
They have been down and secured in this configuration for 2+1/2 years
now with not a problem.
