I'm curious.. How much bigger can a HF antenna possibly be, compared to
a VHF antenna??  I know both of mine have always stood out like dogs
balls, whether they were on the boot of my commodore, or (these days) on
the bullbar on the hilux (http://offshore.pinegap.net/P5198782.jpg - nb:
turn headlights off before driving through water) - not sure how I'd fit
extra antennas there, maybe move some stuff to bonnet side-mount ;)

How good *is* HF coverage? I know pretty much as soon as I head into
Gippsland on my way north, I totally run out of aprs coverage till I hit
just south of Canberra, if I go up through the snowies, or for a small
pocket around Batemans bay, if I'm heading to Sydney, then proper
coverage starts around Wollongong...  I'm wondering if I'm better
getting a 50W amp to go between the D7 and the 9dB antenna, or maybe
it's worth giving HF a try??
