Greetings Marty
I am going down the HF path. Unit of choice is a Codan NGT voice. All up some change out of $4500.00 with a Codan auto tune antenna and rear mounting bracket fully installed and configured.
Join the VKS737 network or similar and RADTEL if you wish to make phone calls.
Positives - Instead of
Sat Phone
Cheaper annual running costs
Cheaper phone calls ( if you want that)
Many other members of the network to converse with and give/gain assistance from/to.
Access to the RFDS
Simple to use with a pre programmed interface. Similar to a mobile phone.
Excellent (Codan) noise reduction system ( important on a HF)
Quality good performing auto tune antenna
Small footprint user interface.
Good retained value
Reliable with excellent reputation
Not so Positive
Initial purchase price (Codan NGT Voice)
Some vehicle computers can be affected by HF transmissions and/or create increased interference ( particularly later model Land Rovers). Unit can only be used with engine off and/or vehicle stationary. ( All brands)
Danfross
fridge compressors can cause interference ( eg
Waeco Fridges) All brands.
ADR’s require that the aerial be mounted to the rear of the vehicle ( no discussion on this one. My research indicates this. Opinions may vary.)
High aerial may hit/damage things if you forget/are careless.
Not as reliable in
communications capability as a
sat phone.

P.S. BPS (Broadband Over Power Lines) is not an issue. There is many years left in
HF radio in
Australia.

Agree with your sentiments, however we usually get only minor intereference with the engine running in our defender.
The other point on the mounting of auto-tune antennas. My research (I've got a bee in my bonnet over this issue) indicates that ADR's play no part in the issue. This is because ADR's only govern the standard for new vehicles. The mounting of an antenna is classed as a modification and thus comes under State legislation via the roads and traffic authority and are not governed by ADR's
So it depends where you are.
Victoria is perfectly clear in what is acceptable, and auto-tune antennas mounted on a bull bar is not acceptable in that State and vehicles that don't comply cannot be registered in
Victoria.
NSW is different, the requirement is to have any fittings mounted as per the RTA guidelines, there is no clear guidance given on what diamenter fittings can be only that they do not protrude past the front of the bar.
They might be viewed as an obstruction by the police, however I have had mine inspected and there is no issue at this point of time. I have rasied this issue with the Minister responsible and I am still awaiting a reply.
My understanding is you only need meet the requirements of the State in which the vehicle is registered.
