Come to think of it, I haven't seen a single Andrew Heliax (12~13mm) grounding
kit that _didn't_use stranded wire, all of which have been sourced new in 
little more
than the last ten years.

I would imagine that for the typical installation, feeder lengths are such 
that the
length exceeds what is recommended for grounding at just each end & that
compared to the cost of the cable, connectors & lost revenue due to down time
more than outweigh the cost of another kit or two.

Perhaps the likelihood of >1 kit in such a typical installation taking the 
makes it possible for the manufacturer to use stranded wire?

Speaking of grounding kits, has anyone here had any experience with a direct or
awfully close strike with a line where the kit was fitted backwards?  By 
I mean that the flying lead from the kit heads back in the direction of 
where the
feeder came from.  I thought cable dressing was important, but an ex-career
Cable & Wireless guy at work says I'm nuts.  I'm tempted to put his tendency
to drive through roundabouts in an anti-clockwise direction together with 
the fact
he isn't at C&W any more, but what do us hams know?  ;^)
