(interference to the radio).

Though 100' of heavy duty grounding strap sounds good, There are two schools of thought.

ON Ham Nation: Bob Heil likes single point grounding , he uses outlet adapters to "Lift" the ground pin on his transmitters so the only ground is via the coax to the tower ground.

George Thomas uses a big heavy ground bus and multiple Straps a-la DX Enginering.

As to who is right and who is wrong..... The answer is actually both, under different conditions. I have to admit there are times when I wonder why the 3rd pin on the outlet.. IE: Laptop computers with all plastic housed bricks and so on, There is no direct connecting between what I'm touching and anything outside of the box.
With the ground pin it's all about line noise and the computer if there is a sub panel involved it has a floating neutral so a ground pin is needed. Me I believe in single point grounds for my home ham gear and tower every thing is linked together including the house power.
