six 8 by 8 foot cooling radiators with automat-

car is my 1941 Ford sedan.  New cars didn't exist and we all kept driving our cars foryears.
View showing how the high-power doubled
feed lines exited the building through a special
glass insulator window especially engineered
for the purpose.  Double quarter-inch copper
wires were used to handle the high power output, and they were clamped together every
two feet to prevent reflections and tune the lines.
