"W5DXP" wrote in message ... A resonant 1/4WL monopole with a good ground plane has a resonant feedpoint impedance around 35 ohms which at 1kW results in only 187 volts at the feedpoint. How anyone could consider 187 volts to be "a lot of voltage" stretches the imagination. If you really want to talk about "a lot of voltage", talk about the voltage that exists at the tip top of that 35 ohm 1/4WL monopole when only 187 volts is being applied at the base feedpoint. I get more than 10,000 volts. Now that's indeed a lot of voltage. -- 73, Cecil, w5dxp.com I am not sure what a lot of voltage is. There are many differant voltages called high voltage. Some statt at 600 volts and some at 35,000 volts. I think that any voltage that can cause heart problems or that you can not hold on to without feeling a shock would be a lot of voltage. The antenna you mentioned at 'only 187' volts would seem to me to be a lot of voltage in the case of a dog peeing on an antenna. Sick you finger in a light socket and see how long you can hold it there at 'only 120' volts. Bet you say that is a lot of voltage. As we all know it is not the voltage,but the current that causes problems. Therefor in the above I will assume the voltage source has several amps of current avaliable. --- This email is free from viruses and malware because avast!
