Which brings me back to my question: How important is the Q and low
resistance of the coil and stinger?
As the loading coil is moved from base-loading to
top-loading, the average net current through the coil
decreases (assuming no top hat loading). The importance
of coil Q is related to how much net average current
is flowing through the coil.
For instance, the net average current through a
hamstick coil is enough to burn your hand even
after the power has been shut off.
I've always had it in the back of my mind to
install a 16'x6' piece of hardware cloth at
12.5 ft above ground above my GMC pickup,
supported by fiberglass poles. I would mount
the loading coil about a foot below the top
hat. I'll bet that would win any 75m mobile
antenna shootout.
