UHF Aerials
Can anyone recommend a decent UHF aerial, as there seems to be a lot of different setups out there?

UHF antenna
I am looking for advice on the best antenna for a UHF radio?
How big or small
Which amount of power or dB gain, 4.5, 6 or 9?
I don't have much knowledge on this subject, so I would appreciate any advice I could get.
Thanks
Bubba

Height is might! I run a 1200mm aerial with 4.5 DB.
Cheers

The key is a good quality antenna that is ground independent it dosen't have to be to high just above vehicle hight would be sufficient make sure you have good connections 4.5 /6 db would be more than enough for most cases. Find out what repeater stations and their channels are in the areas that you plan to travel in.
Hope this helps

When I had my van, I had a 6.5db groung independant antenna, and it worked like a treat. From where I lived in Ringwood, I could get out towards Cambllfield and Blackrock every night. And on the right night could even get down to Geelong. A good quality aerial makes a big difference.

When we went travelling last Xmas 6500km we were losing 300km off a tank of juice with the big wank areil on. 2200mm off the bull bar. Swapped back to the little ariel in Adelaide and saved heaps on fuel. Was getting great reception with the wank ariel but weasn;t worth the fuel bill. Now run a 1200mm ariel.
Cheers

We run about a 900mm unit. A UHF is really for inter-vehicle comms anyway. If you need long distance for emergencies etc, I'd suggest a HF radio or even better a sat phone, even more reliable... Take a mate.

Thanks
Thanks everyone for the feedback. This is a big help.
Is is a bit difficult trying to work out what,s the best equipment, when you have all these facts & figures bandied around which I don't quite inderstand.
I can narrow my search a bit now
Thanks once again
Cheers
Bubba

Most of the guys I wheel with get best results with a 1200 (4ft) ant. with 6dB gain, the 9dB is usually more bulky and less forgiving when flexing around obstacles on the trails.
