[time-nuts] Agilent / HP 117A on eBay...

Marki the antennas are about 3 foot as I recall not huge, really. But
Australia is a bit far away. I would think JJY might be better for you.
That said to actually improve the signal at that distance build a serious
loop. Mine is 10' by 10 ft 800 ft of wire and preamp. Does a heck of a job
for the east coast of the US. Australia is large so you could go really
big. :-) Seriously the larger the area the better. Though the limit seems
to be the turns and the ability to tune the coil with a cap.
There is a lot of good information on a site called vlf.it on loops.
