UHF Aerial

Hi Andy, by end do you mean the bullbar end?

If so, have you got a spring base?

Cheers

If it is a stainless aerial - they aren't recommended for bullbars - they vibrate too much and snap off. Get a fibreglass one.

G'day Andy,

We had a similar concern with our D22 Navara, and found that a short aerial, ie 150mm was the answer. We tried a couple of variations in construction of aerial and found that on that car anything longer simply danced around too much and on mild to severe corrugations would form a double S bend over its' length and then break.

The break was always around the 150mm length, once we fitted the 150mm aerial we did not experience another failure. On the D22 the bullbar moved around a bit and when when you have look under the car you can see why, maybe a similar check of your car could be worthwhile.

Hope this is of interest to you.

Rgds,

Rob.

I would suggest mount to bonnet area Or roof rack

We went through 3 tips on our antenna (2 while in the Kimberley last year!) before I went to TJM and bought a fibreglass type of tip. (I think it was about $27.) The steel tips just swing too much when on a bull bar, even with a spring base. The new tip does not flex as much and the spring appears to be taking more of the flexing, as it is designed for. (We have a 200 series and have lights fitted to the bull bar and they do not suffer from vibration.) Kevin

Thanks for the reply's. I will look at relocating it. I will try to get one in Broome as their is not one of any sort in Kununurra, all sold out for the same reason.

Hello Andy

We broke three different types of antenna on one trip, before deciding the bullbar on our car was just vibrating too much. The vibrating also broke the bullbar mountings (which have since been redesigned).

We now have a stainless antenna with spring base on a zed bracket on the side of the bonnet. It is firmly attached to the car with 2 bolts and plenty of silicone. Iit has lasted several trips with no problems, it waves about a bit but not in a jarring way.

In our case mounting on the body insulates it from most of the vibration which is in the chassis.

Just back from the Simpson desert where we used a quick release mount on the bullbar for the mining flag. The quick release fitting flew apart on the second day so we screwed the flag direct to the mount for the remaining few days where it lasted OK.

Cheers, Gado

I had a few failures before removing the spring base........problem solved..

It now sits rock solid....but my bull bar doesn't suffer from a lot of vibration either....

I followed an idea from pradopoint where I bought some heatshrink from Jaycar, cut it to length of the spring base. First I wrapped the spring with tape then fitted the heat shrink over the top of that. It looks really good and minimised excessive wobble on the aerial. The spring base can still bend if need be but its stiffened up. I even have a flag on the top of the aerial that used to bend the aerial right back when hitting highway speeds but now its all good! A cheap effective fix, good luck with it.
