I have an end fed random wire antenna about 50 feet from my shack into an antenna tuner. I do not have the option to install a ground rod at the house entrance but I do at the antenna feed point. The antenna tuner requires a very good ground so I installed a ground rod there. The question is: should I run a 60 foot 10 gauge wire from the shack to the same ground rod or is it a better idea to get an isolated ground at the entrance to the shack.
I currently have installed a 10 gauge bare copper wire buried 1 foot deep in the clay soil for 20 feet outside the house as my shack ground.
I feel that this improvised ground is better than grounding the radio chassis to the antenna feed point.
