[G4VXE] An unexpected antenna problem

For multiple coax runs along the same route, use different values so one
can tell the difference between the various coax cables.

Good idea but most of those type runs use coax connectors, where
attaching the resistor across a coax connector is tricky. However, it
will work for ladder line.


Good idea that has been around for a long time. Problem for me is that
almost all of my antennas have a matching device or balun that shows up as a
DC short.

No short = buggered cable!

So you'd get the same test result as the resistor approach except as a
go/nogo readout instead of an ohmage.

yes...that has its drawbacks but at least you'll know when your coax
goes open cct. :-)
