RF grounding methods for sailboats: A Summary
You wrote: In article , (Richard Harrison) wrote: If "skin effect" prevents penetration to a copper plate on the hull, fine. RF has then made the transfer to the sea at a shallow depth. That`s the goal. Bull****, where do you guys come up with this stuff....Skin Effect is a a Boundry Thing, and the hull of the vessel is the "Boundry of the Sea Water" even if it is 10 feet below the sea surface. Finally someone gets it! This is what Roy said way back in his first report of his modeling, that the ground plate if fastened to the hull will be on the surface of the water even if it happens to be several feet below. The other side of the ground plate is air. In other words the hull is displacing the water. Unless of course the boat has sunk. For the guys that are referencing the N6?? Article about very short elevated radials over sea water; please note that he is saying those short elevated radials are tuned with loading coils. Elevated radials will not work unless they are 1/4 wave resonant or tuned with a loading coil. 73 Gary K4FMX |
