Hi everyone, I have been reading the sticky posts on grounding as I prepare to assemble a counterpoise for my end fed antenna for hf. I am a little confused as to what the best way to do this is. I have attached a diagram of what I intend to do and would love any feedback as to whether or not this is appropriate? The antenna itself will be about 30 feet up in the sky supported by two trees. I intend to run a counterpoise down the fed and which hopefully I can run along the earth so that I can operate comfortably on the lowest bands. I also believe that the counterpoise should be terminated with an earth ground. In addition, the radio room in my house is on the second story, about 30 feet high. I suppose that I will have to connect the shield of the coax feedline to the house Main ground which is probably about 30 feet from the point at which the coax meets the earth after coming down from the shack and then going up to the antenna. I also suppose that I will have to run another wire from the second story ham shack all the way down to that main earth ground? This seems like an awful amount of work and lots of groundwires running around. Am I doing this correctly?
