I would suggest you taking a look at K0BG's website. He has about everything
you could ask for with respect to mobile ops, from the types of car battery,
to mobile antennas, grounding and bonding, etc. It is a fantastic website
with years of experience noted there. In my case I use inch wide tinned
copper strap which cut to lengths as required. I think you would find the
flat strap superior to round wire due to the additional surface area they
provide. - Mike

"I had noise generated by the disc brakes on my car. When the static level
builds up (frequently) I step on the brakes and it cuts off like a switch.
It does not immediately come back but soon does."
I had this problem with static generated by the tires on the road arcing
over to the drive-line components.
I had another problem with massive static charges on a vehicle, I've been
thinking of the static wicks used on air-craft should this happen again.
Regarding bonding, which is better, flat woven strap or round cable/wire? I
see everyone mention flat straps, but why? I used them on a Toyota Celica
where I operated 6m/2m440 MHz, worked fine. I sold the car to the OM up the
street, he came by one day, popped the hood and I noticed all the flat
straps had shattered in various places due to vehicle vibration. Every
single strap was broken, wire pieces were all over the engine and components
and the straps were like cactus.
I've been eyeballing the various high-current ultra-flexible silicone and
XLPE covered welding wires at a local shop, they also have dozens of copper
connections in various shapes and sizes, thinking of using these when the
time comes.
