I'm putting up a number of verticals in free-standing and 4-square formats.
 My future radial fields will include some elevated systems where practical
and not too obtrusive plus some on-the-surface systems. For some,  I may
use the ON4UN-described combined approach of two elevated radials plus an
extensive ground radial system (the latter connected to the shack end of a
coax choke feeding the antenna).

Question 1: what commercial or homebrew approaches are appropriate for
connecting a growing number (as I get time) of radials at the center of the
field?  I seem to recall an aluminum wheel with 32 bolts at the perimeter
but don't know if or where such a thing is available now.

Question 2: what's the latest thought on whether on-the-surface systems
should be bare or insulated?

If respondents wish to reply directly to me I'll summarize for the
reflector.  Website or article references also welcome.
