interesting format for a new antenna
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. Art unwinantennas.com/ |
