According to probability statistics, the Pearl River Delta can basically satisfy the value of 4-5 Euros. It is suggested that the 2.5 inch pipe be used to sharpen the head into the soil with more moisture. If the latter is chosen, the distance between the grounding rod and the grounding rod should not be less than 180 cm.īut traditionally, the electrical grounding system of electric power and other electrical appliances are 2-2.5m. If you want to reduce theground resistancewhen grounding, you need to use a longer ground wire or use more than two earth ground wire. Moreover, most importantly, unless there is a proper protective device at the top of the earth grounding system, the upper end of the grounding rod should be horizontal or lower than the ground. Generally speaking, the length of the ground wire should not be less than 240 centimeters, that is, 240 centimeters. I was thinking of connecting it to the mains grounding but - I don't trust the installation and this might cause some interference (am I right?) What can I do then? a counterpoise if so what length (ratio) to the main cable, does it have to be in the same line as the long wire or can it be at any angle? What cable would be best for long wire, and what for counterpoise? TIA for all your thoughts and ideas.In fact, the ground resistanceis the criterion to determine whether the grounding rod is in a level state after it is connected to the ground, and the ground resistance contacted varies with the depth of the earth ground wire. So I can hang my long wire in my apartment but now how to ground it? The water pipes aren't metal it's all plastic so I can't do it this way, we don't have any backyard so I cant really leave any cables hanging out connected going into the earth directly, it's hot here all year round so we have no radiators/central heating thus this method for grounding ain't possible. The antenna must be indoors, we have a big roof terrace but the neighbor won't allow it and is capable of destroying it. I live on the first(UK)/second(US) floor, have a really fucked up neighbor and this makes it a bit difficult. I know the basic concept long wire to center of the coax, ground to water pipe or any rod in the earth, but. Hi guys, maybe you could help me with any ideas for making an indoor HF antenna.
