thermidorthelobster:
I was in Widecombe-in-the-Moor car park earlier and spotted a lifted grey Y-reg Disco II running very mud-oriented tyres (can't remember which ones now, but they were 235/70s), with a snorkel, Safety Devices roof rack, Safari snorkel, hefty spotlights, plus 2 CB aerials.

It looked good, the wiring for the aerials / spots was very neat, although there were suspiciously few scratches on the paintwork :wink:

Was it anybody here?

And why 2 aerials?  :?

Big Rich:
If I remember this right.  :oops: You use two cb arials so the signal goes futher ahead and behind and less to the side.  8)  Think thats why lorrys use two.

Hope this helps.

strapping young lad:
i thought they used two aerials for two different radio sets?

if not and they do use two then how would it affect snr etc?

muddyweb:
You can use two antennae in parallel to modify the radiation pattern of the your set-up, providing a more 'directional' system.

In most respects, for a mobile set up, I reckon a single antenna is better as you (tend to) get a more uniform radiation pattern giving a better signal in all directions.

In addition, I can't remember off the top of my head what the licence restrictions are on antennae for CB.

strapping young lad:
ah right i see

makes sense
