And .. when a cup of boiling water, thrown into the air (THE WATER, NOT THE
CUP!) .. NOTHING would come down to hit the ground, when it was 4Ø -6Ø F
below zero .. flat discapeeeered .. that temp stuff was hard on cables too.
Many mike cords, power connectors, etc.. went doo-doo when grabbed before
coming up to "mobile cab comfortable temp" not the wire, but the
insulation. .. .. ... my rotator grease was special, my co-ax loop for the
twist was longer than I would have had in W6, etc.. just wonder if the
other end of the temp spectrum was involved in the deterioration of the
plastic guy lines?
