Tom,
Which company made the cores that you use?

Jim -
Add me to the list, I've had cores disintegrate over the years. I use several
them at the base of my 80 and 160 4-square verticals, wrapped in electrical
tape to hold them together. The problem could have been freeze/thaw cycles,
or heating when one of the verticals detunes when it breaks and I didn't notice
the problem on the shack end.
I suspect those of us in ice/snow country see it more often than the San Jose
area does... Haven't found a good solution yet, I have trouble imaging that
the addition of a box and associated connectors, caulking and hardware will be
more reliable over time.
