Hi Ed, I may have incorrectly anticipated, but you haven't really described any ground out at that remote point that was tied into the safety ground at the service entrance - unless it is in this reference to "little bitty #12 wire." Do you have remote power through 100' of #12? It isn't clear. If you don't and the far end is floating perhaps you are driving a dipole, that too isn't clear - so then, no remote ground is called for. However, as you are 100 feet up, looking over the dunes along the coast (I imagine) out over the sea, this is a natural site for a vertical for DX. Ground would be called for and we return to potential differences. So, to reduce any future "anticipation," is the remote site bonded to the service ground of your home? 73's Richard Clark, KB7QHC |

![]() So, to reduce any future "anticipation," is the remote site bonded to the service ground of your home? Let me rephrase my situation. New house near completion. My shack will be at the far corner from the power service entrance. I was thinking of just putting a couple ground rods ( bonded together ) just outside my ham shack and letting them be my equipment chassis ground, probably through a #6 wire from shack to ground rods. My intent was primarily for DC safety, plus a little 'static' dissipation. As pointed out by one of you guys, I should meet NEC code, which would mandate my bonding this separate ground I would install with the house service entrance ground. My problem with that is that it would require a run of cable from the ground rods at least 100 feet to get down and around the house to the service entrance. This is not really practical nor desirable on my part. While I understand the potential for ground loops, I deem it a rather small likelyhood in relation to the static dissipation benefit I'd get with the closer separate ground I could install. Others here seem to disagree with me, so I closed my previous post with the comment that perhaps I'd be better off forgetting my shack ground and just let the equipment be grounded through the individual power cords to the outlet ground. Now that I may have cleared my situation up, what do you guys think? Ed K7AAT PS: Richard, just missing a view of the Pacific... about a half of a mile away ... and I may reconsider a vertical antenna instead of the dipole I was going to use. |

Ed K7AAT PS: Richard, just missing a view of the Pacific... about a half of a mile away ... and I may reconsider a vertical antenna instead of the dipole I was going to use. I still recommend just using the outlet ground. I don't think you'd accomplish anything by adding the ground rods you mention, and it might even cause a hazard as some others have said. It certainly won't be any better than your household wiring system ground for safety or static discharge. What I would do is make sure all your equipment is grounded through the household wiring safety (outlet) ground. Its purpose is electrical safety, and that's what it's designed, installed, and inspected for. Ungrounded equipment can be connected to grounded equipment or to the mains safety ground -- if it has a power cord, replace the cord with a 3-wire cord and connect the safety ground to the chassis and cabinet.

This is not really practical nor desirable on my part. After you take your first couple of lightning strikes you will feel that a 100' of #6 ground wire to the power ground for the antenna system ground is a simple requirementl. I will probably never build another house but if I do, the first consideration will be proper grounding for both NEC and lightning protection. Experience has led me to believe that if you cannot tie a new ground rod back to the panel ground you should not have the ground rod.
