grounding

Use fine multi stranded wire of about 14 gauge or even larger if possible. Use as short a piece of wire as is necessary to reach from radio to closest practicle grounding point in vehicle.

I have been running HF mobile for over 30 years and have not found that a separate ground was necessary. The most important ground is at the antenna, especially on 40 meters and below. Here it is important to have a low inductance ground, that means as short and wide as you can make it.

My current HF mobile setup is is mounted on a plastic toolbox and wired into the truck main power buss with 2-12ga wires each, on the positive and negative. Battery charger clips go to the mounting posts inside the dash. It is secured on the passenger seat with the seat belt.

I talk the world with this setup, every day and put it in and take it out of the truck, every day.
