Mounting autotune on rear of 90 series

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.

Look in my profile there are some pics of it in there.

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

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
