UHF antenna

to follow up.

Generally car UHF antenas come as 3dB, 4.5dB, 6dB and 9dB.

Imagine you had huge balloon and you pinched it in the middle so that the two opposisite sides touch (so it looks a bit like a doughnut.) It's kind of round except for the pinch in the middle.
That is the range of a 3.5dB antenna. It's almost the same in all directions.

Now if you were to flatten the balloon between two horizontal planes so it's squashed in the vertical plane but allowed to stretch in the horizontal. You still have a doughnut shape. It's not as high but goes out further.
This is the range of your 4.5/6dB antenna.

Now if you were to squash it further between the two horizontal plains. As hard as you can so it's almost completely flat in the vertical but spreads really far in the horizontal plane.
This is the range of your 9dB antenna.

As you can see a 9dB antenna will have greater range (horizontally) but only if it is dead vertical. As soon as it is tilted (like going up a hill or on rough terrain) your transmission will go high up in the sky and down into the ground. A reciever on the other side of the hill is unlikely to pick you up.

So. A 3dB is great in hilly country (but the range is limited) and a 9dB is great for flat country (but the antenna has to be dead straight)

I have a 6db and a 9db that I use.

There are other issues to consider like, ground indepenance, strength, flexibility, location etc. but I'm sure other will explain further.

All the best.

Yeah thats what I thought.

I notice a number of 4x4 have two arials fitted. Is it possible to have two arials for the one radio???

The 'other' antenna is probably for cell-phone !! Looks very similar to a UHF one.

Where do I get the Bundy signs?

Off of utes...haven't you been listening LOL

Dunno maybe they give you them when you buy the aerial or vice versa.

You also need one of those forward angled bullbars off a Mack to mount them on preferably one on each side.
And a dirty white cowboy hat.
And a scruffy blonde.

I reckon they hand them out at the B&S Balls with the ear tags and Conargo pub stickers....LOL

Where do ya get the scuffy blonde?

You have to do something for yourself, so look around Lots to pick from LOL.
