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.
