Hi guys
Just after some ideas for mounting a codan autotune on the rear of a 90 series prado without using a Kmar bar.
Has anyone done it? Any pics would be great. I'm just going through the brain storming stage at the moment. I'm thinking a bracket coming up behind the spare or possibly out from the door hinges as some 100 series do.
Thanks
Tim

Tim have you looked at the Kaymar centre wheel mount?

Look here forHF Aerial Centre Wheel Mount

Scroll down the page to find it.

My concern with the K mar set up is earthing and also the dreaded flat tire. I am presuming the antenna is disconnected at the base then removed prior to removing the spare? Its going on the Mrs prado so I'd prefer to keep it nice and simple. I figure she won't at all be impressed with a flat let alone taking the antenna off to get to the spare. Thanks for your suggestion, I haven't written the idea off yet.

I have one on the back door of the GU Patrol holding a Barrett autotune antenna.

CJ 4WD Accessories 0419 008009. They were very helpful and the bracket turned up very quickly.

I made a bracket for my 100ser that fits between the body and the lower taildoor Its lying at home somewhere.
Used existing bolts

Made it out of 3mm steel and bent it up with a gusset and it would have been Ok .

Then got a Kaymar wheel carrier so didnt use it

Had to go find a photo of a 90 series. So does yours have a swing away door with a lifting window? If so could build a bracket coming off the bolts that hold the spare wheel on with. I have done this on my Isuzu MU, to late to go take a photo now but will do so tomorrow.

Thanks mate, the prado has a swing away door and the window stays in place. Similar to the GU or GQ but only one door, if that makes sense?

Tim, I am not sure if the carrier on the Prado is bolted to the door as with the MU......do not take to much notice of the extra bracket on the bottom as it is part of a mod to centre the spare wheel.Image Could Not Be Found

Tim,
Behind the spare tyre bracket is the best option and is used by a company in SA that makes the brackets comercially. I've had a bit to do with 90series Prados in teh past. For a Codan, the bracket is best coming out from the LHS of teh spare tyre because of its size. A Barrett on the other hand is best coming out from the other side because of its size and shape. I'll post some photos of each installation.

When it comes to earthing, I stress the only option is a heavy cable to the bolts that hinge the tailgate on the body side - that is the best way to use the whole engine body as the ground plane.

Here are photos of a mate's Codan and also of the bracket I made up for my Barrett:

Hope it goes well

Phil
Thanks
for your photos, I have my codan auto tune back now and its time to do some work.....
Are you able to send some more pics of the prado with the codan or even a sketch or something? I have had a bit of a look at it and the only issue I can see is the the spare tyre is "counter sunk" a little bit meaning the bracket has a very secific maximum size and the bends would have to be like art work to prevent it hitting the body of the car with vibrations and all that.
It's either going to be in the centre like your mates or coming out from the centre of the spare. I know u have to take the antenna off to change a tyre then but realistically, how often do you change tyres? On big trips I have another spare on the roof anyway which can be changed first.
Thanks
Tim
