So far so good. I received the cables and other adapters needed to make the device usable here at PVC towers. In short order, it has given me a much better idea of what my antennas are really doing. Case in point, when attached to the radio room end of my LF longwire, things looked a bit strange. Lots of peaks and troughs. Connected to the receivers, no signals.... A notion emerged. Sure enough, the down lead had disconnected from the transformer box, likely due to some dog related activity. There's a deliberate weak link here so any breakage occurs at an easily accessible location (and doesn't bring the lot down). With that fixed, all back to normal, and the VNA plots looked much more like an antenna.
