Re: show your mobile antenna array
You want to be sure to fuse AT the battery (both
positive and negative leads), THEN power the switch etc. I use
50A self-resetting circuit breakers. This protects the line
used to power your gear, not the radios (use the appropriate
fuse AT each radio).
You want to use both leads for maximum noise
reduction (the battery is a huge capacitor) and lower IR^2
losses (not returning through the vehicle body). However in a
new vehicle, which may measure alternator load, you want the
negative at the chassis ground point so it can be included in
the load analysis of the vehicle computer.
You want BOTH leads protected from accidents; if the positive was shorted or consider what could happen if the vehicle ground lead disconnected; all the current (of the starter for example) would pass through your radios; definitely a 'not good' situation.
(You also want a larger extinguisher, if you're ever planning on putting out more than a cigarette or small campfire; they go quickly and change it at least annually, the road vibration packs the powder down hard making it ineffective.)
