Gday Jim,
Ill throw my two cents worthin, Go the 706 11 G if you are going to be
it for Ham use, much smaller and so much better to use as a Ham radio,
is also easy to interface.

The Codans are a commercial radio and have features like a commercial
if you will be using the 4wd networks etc you should really use a Codan or
Barrett as the 706 isnt type approved for Commercial HF use, BUT if you
just going to use it for Ham i would use the 706 or any other mobile HF
a Yaesu etc.
The later model Codan antenna the 9350 can be used with most Ham mobiles
like the 706 with just an interface cable or adaptor needed to plug into
accesory connector, ( Google 9350 and 706 ) you can then use the tune
function on your 706. The earlier 8552 which have the straight not tapered
auto tune section cant be used as the control is done externally, plus as
Marc mentioned they are a bad beast, I should know I use one !
