Thats right Kev, in fact, weight for weight, its a far better conductor than copper!

Range Rover Blues:
A CB ariel needs a decent ground plane ie a large flat bit of steel. Aluminium doesn't work! and the CB needs to be connected electrically to the ground plane, If you mount the CB on the roof bars it will try to use the roof as ground plane, not the bar.
Jake:
I used to have a aerial on my roof bars.
I connected a wire to the bottom of the aerial and ran it to a grub screw, just behind the roof bar.
Not the best idea, drilling into your roof but the cb worked great.

Hence all the advice about hooking everything down to the chassis/block to maintain a good RF ground.
Well I must admit, you've got me going again now, might just pull the old rigs out and hook 'em up again. Might even renew my vhf 2m license for mobile ops.
[!Expletive Deleted!] - I can see some spend coming on - better not tell SWMBO - ended up with a 27' antenna and a 4 element Yagi beam on the house roof last time :twisted:
