Grounding Question

I am in the process of developing the layout of my shack along with putting up permanent antennas. My house is on the older side so it does not have a dedicated ground rod. I have been debating on running off of strictly battery power. My question is if I set up a ground rod for a new antenna tower could I bond all my equipment to it and be fine? Since I am running off of batteries it wouldn’t be powered from the house so my assumption would that it would work
