Amateur radio antenna grounding.

New User
I have a Amateur ham radio antenna attached to a shed,in the rear corner of my property. It is mounted on a water pipe mast at 50’ in height top of antenna. I have the coax and pipe grounded at the base to 2 ground rods. with a lightning arrester mounted to the coax. #4 stranded ground wire running to a detached garage and attached to the end of my underground electrical service ground Rod. Mounted to the wall is a single point ground bar, next to the electrical service where coax enters the garage, attached to another lightning arrester.
I have a 10’ separation from the garage to my house.
My question I cannot find a answer too is : Do I need to continue to run a ground wire #6 minimum, around to the front of my house, and attach to the main service entrance grounding system?
Thanks in advance,
