When reviewing the shield of coax I see that the circulating strands
follow the same principle
that I advocate for small full wave antennas. Each turn on the
shielding has a compensating return
turn which cancels the added inductance while the wire crosses over
each other to cancel the added capacitances.
If one got a short length of say 2 inch diameter sheathing they could
attach the wires into one complete circuit
for an antenna. One could dip the sheathing into some sort of
insulation if they so which but actually the wires each act as
insulated wire (electricity preferrs not to turn at right angles if it
can go straight) so that is really not necessary . If you feel the
need to experiment on a mobile whip that does not require a ground
plane then here is one that is full wavelength and really small
compared to a Bug catcher ! Give it a try and take it to the next club
meeting.
