[OZAPRS] Was Byonics, Australian requirements

[vk7arn]

VK7ZRO-15 is on the road with HF and will be several weeks.  ZRO is one of
those
amateurs who likes to build his own and keep gear expense to a minimum.
If
there's interest, I'll ask him to summarise the set up he's using.

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??

Regards,

Damien
