Couldn't the same principle be used for lightning?
Though, I can sort of see how you could get the distance,
you calculate the direction with only one antenna?

Interestingly enough, their screenshots show location of strikes - how
do you do that without distance, (considering you're only using one
antenna) ?
How do they configure their 'Close Storm Alarm' if they don't calculate
distance?
And in fact from their WWW site: "Special processing in software reduces
the effects of strike-to-strike energy variations providing more
accurate distance information."
** Ummmmm - it could be a directional one.
It is: "StormTracker's direction-finding antenna provides direction
information while storm distance is calculated from received signal
strength."
A dumb question but, without actually moving it about, couldn't your
reading be 180 degrees out?

For the purposes of the OP, I would think that possibly using an
'average' lightning disharge strengh and calculating from the received
signal strength. Not, 100% accurate but possibly close enough for
curiosities sake.
And in fact from their WWW site: "Special processing in software reduces
the effects of strike-to-strike energy variations providing more
accurate distance information."
Looks like they do use something similar.

It used a loop antenna plus a secondary antenna to resolve the 180 degreeAnyone in Aus built one of these or know of a suitable schematic.

It used a loop antenna plus a secondary antenna to resolve the 180 degree
ambiguity. Apparently this is a standard RDF technique.
By wayback I'm talking maybe 20 or more years, so be prepared to dig. Good
luck.

Hope this helps,
