I know that you have had a long and very varied career in electronics.
Have
you ever had any experience with cable-suspended traffic lights in
Florida
or elsewhere in the USA ? Or anyone else on here even ? The question I
have
is not particularly repair related - more one of general interest really,
so
I'm happy for any responses to be direct off-group if it is felt more
appropriate by anyone.

Tell us all, we can skip past it if we don't like it. This is an
eclectic group.

OK then. Michael has already come back to me off-group with some useful
insights, but any others are of course appreciated. On one of my recent
visits to Florida, someone else in the car asked me the reasons for the
large cable loops either side of traffic lights which are suspended across
junctions on catenary wires rather than gantry or 'fishing pole' mounts.

I guessed perhaps drip loops, sophisticated strain relief, or maybe to allow
for cable breakage rewires, but I had to admit that I did not really know,
and that I would try to find out when I got back. So, does anyone know for
sure, or is it just that it's the way it's always been done, and the real
reasons are now just lost in signal repairman tradition ?
