HF autotune on a tray body ute.

Thanks for that. That's sorta what I was thinking of doing but I've never seen one there. A couple of questions if I may.
Why did you decide on the left side?
Did you mount it to the tray only or did you brace it to the chassis or whatever?
Is it a steel tray or aluminium?

Thanks gain.

Bungarra,
I too was looking at the options to install my Barrett autotune. The way it was explained to me by Electric Bug, was that the Barrett autotune radiates its signal from the casing join upwards and for best transmission, you need clearance from any metalwork at a 45degree angle in all directions from this point upwards. So you need more clearance at the top of the antenna, than the 160mm specified lower down.

With a mount on the back of a stationwagon, the sloping rear glass allows this clearance. If you mount against a vertical side, such as a metal canopy, then you either need to space the antenna further out, and tilt the antenna away from the canopy to get this clearance. Fibreglass canopies do not have this issue.

I installed mine on the back of the canopy, and it leans away. I can also loosen my custom bracket to raise the antenna, so it has good clearance away from the canopy. In the position that you have yours, I have seen people with a swing bracket or a mechanism to raise the autotune, to obtain good clearance.

Receiving is not an issue, but having it close to metalwork will affect the transmission of signals.

Cheers

Hi Phil

thanks for your reply.......easier to understand the situation the way in which you have explained it

Hi Guys
photo turned out bigger than I thought but a bit hard to show detail, If you want I can take a closeup with phone camera (this was by phone) let me know
Take Care

Picture is good thanks

Hi Carree

Picture is perfect thanks...leaves me a little confused as if you look at the picture of my rig my antennae is almost identical in position to yours........

Comments from Phil (see earlier response) made a lot of sense but then your pic with your placement leaves me a little bewildered as yours works......why doesnt mine?

Not an issue with my set because as soon as I sit it well above the roof line it is perfect!

my rear canopy is made of aluminium

thanks

i can email you some pics if you give me your address. the mount also acts as a step to get to the top of my canopy.

Thanks qubert.
