Here's what Jerry had to say and I agree:

If you really want lightning and RF grounding, those ground sources need
to be connected together with wide copper strap. 18" is a nice width.
Otherwise the inductance is too much to be totally effective.

The 18" copper strap that Jerry suggests would be nice but would also be a
nice investment today.
In my case I use a piece of 1/2" copper refrigeration tubing to connect/bond
[actually via CAD WELD} all of my driven grounds. There's 3 at the base of
the tower in a ring and 1 at each corner of the house. The house has a
series of lightning rods across the top. All of these points are connected
together. Also, the mast out the top of the tower has 2 bonding flexible
straps between the mast and the tower sleeve. This assures that the mast is
bonded to the tower and the path is not through my rotor.
Yes, in your case, the path between your service ground and your antenna
ground is through your station equipment via the coax. Not good!

Hi Bob,
My antennae use the same radial field of 60 or so 130' radials. The
radial plate is 360' from the house. The only connection between the
house and the radial field is via the coax shield. Are you suggesting
I run a length of additional wire from one of the radials to the
grounding point of the service entrance ground rod?
Gary, KA1J
As to having a RF ground, a ground radial system below your antenna is
the
reference point for that antenna. Several antennas can share the same
radial system. Also that radial system must be bonded back to the
service
entrance ground.
