However, I still think that with only the vertical element connected to the
centre conductor, the vertical element radiates although not very well. With
only the radials connected to the outer braid, the radials do not radiate.
The RF live of the transceiver is normally connected to centre conductor,
and the RF ground side (the 0V side) is normally connected to the braid. The
outer of the connector on the transceiver is possibly connected internally
to the case and mains Earth.
