I have a good quality GME fiberglass aerial mounted on my bullbar already and I was considering adding a sandflag for bush driving and to gauge the hight of my caravan and roof racks.

Can you see any problems with just slipping some electrical conduit or similar PVC pipe over the end of the aerial to raise it up to the hight required ?

I would rather scrape the conduit and possibly damage the radio aerial than drive the van under something to low and damage that :-)

Yes I can. In fact, if I understand your post correctly, it would be foolish to go down that path. Firstly, because GME aerials aren’t cheap and, secondly they are not designed for that use.

If I was you, I’d buy a sand flag and attach that to the bar (as a seperate item). Then cut it to the length you require.

Adding additional weight to an aerial will cause it to fail very quickly over rough ground.

I did experiment with using conduit as a sleeve over an antennae to mount a sand flag. It didn't work. The antennae could not hold the flag properly. It flopped about all over the place and was more trouble than it was worth and that was just messing around near home.

Find a way to mount it independantly. Also, when I got mine up and working OK the flag got cut to pieces on overhanging branches. If you can mount your sand flag in the centre of your bullbar so it has as little contact with trees as possible.

Actually I plan to use this on the road more than off the road :-)

I have a fear of driving under things low while towing the caravan.

I am after an early warning system!

In your post you talked about adding a sand flag for bush driving......?

Either way, I've given you advice, what you do with it is up to you.

To allay your fear of driving with the height of the van just measure the height and add a couple of cm , and put a warning sticker on the speedo where you cant miss seeing it , some thing like "min height 3.2mtr" soon stops you driving into underground car parks ect.

mmmm my resumé reads "Doug is not smart but is good at lifting heavy weights"

That is a great additional idea but I will use it as a backup system.

I n=know what I am like :-)

Doug,

Something like this on ebay might do the trick.

They are light and you can use only the length / diameter you need by removing top or bottom sections. Collapses down to about 30cm when you are in the country too.

Search for collapsible fishing pole in ebay dot com , not dot au for alternative sizes. I got one for about $8 inc postage from HK.

Add a thin wire to it and it makes a great collapsible antenna too.

Sorry Doug, search for telescopic fishing pole, and that one is 60cm when collapsed.

I will have a look

I was thinking if I just get a solid second hand fishing rod at a garage sale and cut it to fit.

thanks :-)
