Step 1 for taking a bunch of guesswork out is to learn about the theory. Step 2 once step 1 is learnt is to use the right tool for the job.


Had you don'e that you would know that making sure you have DC conductivity to the battery does absolutely nothing for ascertaining whether you've got a good RF ground or not. That can only be done by putting a whip in the mount, getting an antenna analyser and measuring what the feedpoint impedance is at resonance, therefore removing a whole bunch of guesswork right there. A quarter wave over perfect ground is 36.8 Ohms when the antenna is at resonance ( X=0 ). Anything other than that and you've got losses and its usually in the ground for the antenna. You could stick a wire directly from the mount to the battery 3ft thick and it wouldn't improve the RF ground.
