Thanks for the rapid resizing, Mike; much easier to read.

The "swivel hinge" is a clever solution. The Australian hams think the US hams are crazy to maket it so hard to bring the antenna down for adjustments. They use a pivot and counterweight system, for a welded pipe mast, that requires very little winch effort to go from vertical to horizontal and back.
