In your statements, you never specify what a "large conductor" is. Here you a "". In electronic circuit theory, a "ground" is usually idealized as an infinite source or sink for charge, which can absorb an unlimited amount of current without changing its potential. Where a real ground connection has a significant resistance, the approximation of zero potential is no longer valid. Stray voltages or earth potential rise effects will occur, which may create noise in signals or if large enough will produce an electric shock hazard. The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices such as cell phones and media players as well as circuits in vehicles such as ships, aircraft, and spacecraft may be spoken of as having a "ground" connection without any actual connection to the Earth. This is usually a large conductor attached to one side of the power supply (such as the "ground plane" on a printed circuit board) which serves as the common return path for current from many different components in the circuit." From: http://en.wikipedia.org/wiki/Ground_(electricity) In this case what is being discussed is electrical safety, not radio. Portable radios do not have a "large conductor". Portable radios do not have a "large conductor". Today, transmitters are often very small and still they work OK without any earth connection. How large should a "large conductor" be? Adequate to electron emission. There is no electron emission. Probably it is the coax: "Many conventional coaxial cables use braided copper wire forming the shield". The transmitted signal flows only along the inside of the shield of the coax. The outside is supposed to carry no signal. If it does, there is a problem with the antenna system. The outside is the "large conductor". Portable radios do not have coax. I also belive in each Tesla's word. He discovered that in his secondary coil is the oscillatory electron flow from the earth into the air. Why is it impossible? S* We do not operate our transmitters in the region where electrons start flowing into the air, because we do not like arcing. Tesla did, but he was in a different business. Electron do not start. Electrons are flowing into the air (and vacuum) at each voltage. No, they are not. The thin wire is the best "cold cathode". Gibberish. What are your antennas made of? Usually aluminum tubing or copper wire for fixed antennas and usually chrome plated steel for portable antennas. Antennas do not have a chassis. |
