Has anyone mounted a Codan Auto-tune on a Deluxe ARB Bar?

ARB says the standard aerial mounts on its Deluxe Bull Bar are not strong enough for the weight of the Codan Auto-Tune.

Despite this I have seen a few vehicles in member's profile photos which have an Auto-tune on what looks like an ARB Bar.

I am certain ARB used to offer a special HF Aerial mount as an option for its bar, but the Artarmon Dealer tells me they don't offer it and it doesn't appear in the latest catalogue.

I want to move my auto-tune to the front as it is too high mounted at the back and the rear mount flexes alarmingly. I know there is ongoing debate about the legality of having it at the front - where until very recently absolutely everyone used to have it - but ignoring that for the moment can anyone offer any insight as to the practicalities?

All comments gratefully received.

cheers

Ben

For my Autotune antenna- I made up a substantial 1/4" aluminium plate - and attached that to the (ARB) bar with 1/4" U bolts.
Very successful and no probs after many kms of rough usage.

Codan recommend (in their 9350 manual) to "Mount the antenna on a strong metal bracket about 10 to 12mm thick........"

We also welded a stronger plate to our ARB bar.

Legality of having it on the bull-bar....our vehicle is registered in NSW therefore I must meet the NSW regulations. I have never been able to find anything that prohibits it, although there is a grey area with regards to obstruction of vision... from a practical viewpoint that has never been an issue.

Landy, I don’t doubt what you say. However, under SA law (very similar to others) an official could easily class it as an inappropriate attachment to the bullbar (i.e. rule says “An object fitted to a vehicle must be designed, built and fitted to the vehicle in a way that minimises the likelihood of injury to a person making contact with the vehicle.”)

I reckon the humourous description on one website, of a bullbar mounted autotune being an “Emu attractor”, is worth thinking about.

It is a grey area....

The same argument could be made for the bullbar... but let's face it any contact between an vehicle and person will see a poor outcome for the person, regardless of what is on the bullbar.

Victorian registration rules are quite explicit, a few years back I took the step of asking the NSW RTA, and the police for guidance. The guidance given lead me to keep it on the bullbar.

There are legalities in mounting the autotune on the bullbar. Most states talk about the diameter of an aerial mounted there (pedestrians) and vision obstruction. My 9350 would fail both of these.
I believe that guidelines are still evolving in some states, with a Federal standard on the way ? (or maybe it's been out for some time...can't remember) any way.............
I moved it to the back because in the event of an accident or collision with a pedestrian, insurance companies can wipe you faster than you can say "huh?"

Mine is mounted on the ARB bar, but I had to have a tag welded there especially for it. I would really prefer it on the back of the vehicle, but have no way of doing so at the moment.

The antenna must not protrude over the front of the bar, obscure headlights, or impede drivers vision. I believe there is an attempt in process to have all states legislate to have all antennas monted on the roof or rear of the vehicle in the cas of HF.

that will break in time the weld on the arb bar and material used is not enough.

Thanks for all the replies. I think I will just get a strong bracket welded on to the bar and hopefully it can be painted in a way that it doesn't look like too much of a bush job.

In NSW there are restrictions on the width of an object that can be in the driver's field of vision and an auto - tune will exceed this. BUT so do ladder racks off the bull bar of every 2nd tradie ute I see.

There are rules, and then there is enforcement of those rules. I really believe the wallopers have better things to do, unless you bring yourself to their attention, you'll be fine. RE minimising impact to pedestrians, it seems that as long as nothing is protruding forward to potentially "skewer" a pedestrian, then its ok. Happy to roll the dice with my insurer - unless someone can prove the reduced visibility was the CAUSE of an accident, no problems.

Hi BenDid

I'm not sure that information is correct regarding the size, can you point to the actual regulation.

I looked into this extensively a couple of years ago, so perhps something has changed in that period. Certainly that is the case in Victoria on the size, but there was nothing that specific in NSW.

Nothwithstanding I have taken the same view as yourself.....

Hi Landy,

Well I am glad you challenged me on this because now I am not so sure. I could have sworn black and blue that there was a NSW standards / info sheet in similar terms to the Vic one.

BUT - I have just trawled through the NSW Transport & RTA web-sites and cannot find anything like it anywhere. The really irritating part is that I was sure I downloaded a copy but I can't find it on my laptop.

So, if anyone has a copy of the NSW standard or ADR re driver visibility, would they kindly post a link to it?

Cheers

Ben

Hi BenDid

Following is a New South Wales RTA Vehicle Inspector’s Bulletin which relates to bull bars and accessories fitted to them.

It gives guidance on fitting accessories and suggests any bull bar or other attachment must allow the driver a view of the road and of the traffic to the front and side of the vehicle so that the driver can drive the vehicle safely. Whilst subjective, it does not stipulate any dimensions.

In terms of ADRs; these are Federal Government Regulations that relate to how a vehicle is designed and do not cover the fitting of vehicle accessories. The fitting of bull-bars and accessories to vehicles are covered under State Government regulations and are the responsibility of the traffic authorities in each State. This is why there is a difference in requirements between New South Wales and Victoria, for example.

Others may correct me on this, however my understanding is that as my vehicle is registered in New South Wales I must comply with registration requirements in New South Wales. I doubt I could be ‘booked’ in Victoria for non-compliance with its registration requirements because it isn’t registered in that State.

Hope this assists….

Vehicle Inspectors Bulletin Nbr 5

antennas on bull bars do not restrict vision , it is to do with lighting and more specifically spot lights mounted on bull bar top rails, radios are seen as emergency equipment

Hi Ben DiD,

although my ARB bar is a Commercial Bar there's not a lot of difference. I had a substantial bracket welded to the bar to support my Codan Auto-Tune and this has not given any problems in the three years it has been there. The bracket fitted up perfectly for the welding, too. The bracket cost about $25 and was supplied by ARB Gawler, now ARB Elizabeth (Brad Newham).

Hope this helps.

Ben - I had mine on the ARB Bull Bar for a while - got in the way of a lot of vehicle taken photos.

I assume you do not have a ute - There is a few good posts showing some good rear mount brackets for a Station Wagon on this site.

Otherwise I put it on the back of my tray between the camper.

The autotune on the ute tray is a good example of where not to put a HF antenna.With metalwork so close the radiation pattern would be seriously compromised.

The metal work (in this case the rollbar and roof ) is right next to the radiating part of the antenna.In the 9350 and the older model codan shown in the photo the radiating section of the antenna extends almost to the bottom of the black plastic section.This reflects a large amount of the signal giving a poor radiation pattern.

Thanks Tony,

No ute (SWMBO ruled that out) , a NS Pajero in turbo diesel.

The aerial works fine where it is its just that I keep scraping the top of it in shopping centre car parks and the bracket its on flexes a bit. Unfortunately I can't get a kaymar style mount for the Paj so on to the bar I think it has to go.

cheers

SteveL. Thanks for the info - Its an alloy Bar & tray, that may make a difference. It works well enough where it is for what we use it for, which is the occasional listen and if we get an emergency. Cheers Tony

When I had the profile updated in mine by the Brisbane service centre I forgot to take the whip. No prob said the boss these are tolerant enough to work a bit without it.

I asked about a rear mount and he said it was fine as long as a few inches of the barrel and all the whip was above the roof line..

Hes the man so I guess he knows.

From the research I have done the ADR rules prohibit anything thicker than 30 mm being mounted in the drivers vision.
In the pic they provide it is effectively anything above bonnet line and extends right across the front of the car.
Incidentally this also applies to driving lights which protrude above the bonnet line also.

The coppers in the Territory have an exemption to allow theirs to be in the front.

Sorry I cant and had a look through the minefield but pages seem to have changed recently.

I did research it and as a result put mine on the rear as per the pics in my profile.

However Ive got it for sale if anyone is interested

Hi Graham

My understanding is that bullbars and accessories attached to them come under the jurisdication of the relevant State Motoing authority (RTA in NSW). ADRs are producedunder Federal Law and set standards for vehicle manufacture.

In NSW the RTA does not specify dimensions, in contrast Victoria does.

Vehicle Inspectors Bulletin 5

If you come across the ADR you mention I'd been keen to see it as something may have changed.

Hi,

If your vehicle is a Diesel, I would be somewhat cautious about bull bar mounts/mounting.

In my experience of mobile installations, diesel bull bars are hostile places for any antennas, particularly those with moving parts. (The Codan uses a motor to wind up/down a tuning slug)

Barrett in the early days had to redesign their antenna mounts to deal with bull bar mounts.

A collision with a large kangaroo could well damage your antenna making it useless when you may most require it.

IMHO the rear of the vehicle is the best place for your antenna.
