Standing morphing to travelling waves. was r.r.a.a WARNING!!!

Let's consider a 50 ohm ideal transmission line with a 25 ohm ideal resistive load in the AC steady state. There is no "antenna system inductance and antenna system capacitance", there is no load inductance or capacitance at all. I suspect what Dan is referring to is the LCLCLCLC equivalent circuit for a transmission line. A horizontal wire over ground is a one-wire transmission line with Z0 = ~SQRT(L/C). A radiating antenna can be considered to be a lossy transmission line. A #14 horizontal wire at 30 feet calculates out to be Z0 = 600 ohms so L/C = ~360,000. I'm pretty sure that is the L and C that Dan is talking about - the same L and C in which the standing wave energy is stored. -- 73, Cecil http://www.w5dxp.com |
