Why not make the ground rod functional.

I use a 3 band (144/223/440) J-Pole on top of my tower. 
I have a TH-6DXX with a 2M 14el beam above that and 
then the J-Pole on top.

I built it using 1/2, 3/4 & 1 in. Copper tubing. 
It is assembled using standard plumbing adapters.
It is bonded to the Mast, which is also bonded at the 
bottom of the tower where the Prop Pitch rotor is mounted.

The three coax cables (RG-213) come all the way to the
bottom of the tower and grounded by a feed-thru lightening 
arrester. The Coax from the 2 beams are also grounded the 
same way. I have a coax loop on each one before it goes 
underground to the house.

It has worked well for the past 30 years.
