Could it be that a monopole is a "STANDING WAVE ANTENNA"? Here's an EZNEC simulation of a 1/4WL monopole. It is a 1/4WL stub with the wire resistivity adjusted to simulate monopole radiation. The standing wave current distribution (lack of phase) and feedpoint resistance are similar to a monopole. http://www.w5dxp.com/stub_dip.EZ Add a short at the top and a load of 600 ohms in the shorted segment and observe the traveling wave. http://www.w5dxp.com/stubsht.EZ Turn on the current phase display and observe the traveling wave phase shift. -- 73, Cecil http://www.w5dxp.com "Government 'help' to business is just as disastrous as government persecution..."
