Me gabbing on about the RF field around a mid-loaded dipole antenna (which just happens to be being excited parasitically by a vertical in close proximity) while waving around a fluorescent tube in the dark.

Input power to the vertical is about 1 Watt on 30 metres (~10.140 MHz). The loaded inverted-vee dipole is resonated by a z-match style transmatch at the feed point, but is otherwise undriven, the transmatch tank is just floating, no transmission line is connected. Afterwards the dipole was detuned to prevent interaction with the vertical and QRSS signal reports improved.

  • How you get free power !!

  • nice, it's like wireless energy transfer

  • Very interesting ... the coupling that is. Something to test for the next time things don't quite behave as they should according to theory!!

    Thanks for taking the time to do the vid and the write-up ...

  • cool but scary
