I recon you would be hard pressed to find a mobil phone aerial that was not ground independent.....does not depend on a flat metal ground plane for its operation.
on thing you need to be very aware of is that mobile phones and wireless internet run on microwave or near microwave frequencies and that means.
the transmission is very much straight line, line of sight to the tower.
cable (and other) losses are significant
lots of the mobile phone aerials come with very very thin coax cables for convienience of install......these must be kept short.
remember most dongas are made of metal clad fridge pannel and are pretty much faraday cages......if you are worried about, induced electric fields, cosmic rays, man made radiation causing cancer or aliens reading your mind from outer space.....live in a donga........they work better than an alfoil beenie...true.
get any aerial outside that donga and you will be better off..unless of course there is a window facing the right way.
there are heaps of options..how
well any of them will work will depend on the situation.
Do you, can you get the same donga each trip?
one issue is how you will cable it out of the donga and how to mount it.
With some luck you might get a window facing in a suitable direction.
you could use an on glass, thru glass like is often used on cars, and buy a supply of replacement adhesive pads.
I'm not over confident on some of those because I recon most of the gain in the stick will be lost in the thru glass and the spindly little coax.....but if it gets you out of the donga and line of sight it will be an improvement.
if you can drill a hole or find a crack..you might be able to use some sort of magnet mount...unless they used aluminium for the fridge pannel.
one thing I have heard off is getting either a blue tooth or wireless ethernet access point type modem and putting that outside on a battery and connecting wireless.......if wireless ethernet, that could be placed hundreds of meters away.......ya just have to worry about someone nicking it....or cracking the security.
the first thing you need to find out is, where the
telstra tower is relative to where you are working, and what the scale of the problem is.

"Do you, can you get the same donga each trip? "
Unfortunately Bantam we are in another part of Australia sometimes as often as every 2 months, mounting shouldn't be a problem, and as you say getting out of the donga is going to provide the biggest gain.
There is always a crack or flyscreen i can poke a cable through.
Because of the swift movement of our crew I sometimes dont have a exact location of our rig... let alone the surrounding towers.
