writes Reg Edwards wrote: Antenna conductors ARE transmission lines and the same sort of calculations apply. You're right, Reg. Without reflections from the ends of a dipole, the feedpoint impedance would be hundreds of ohms. A standing wave antenna is like a lossy transmission line where the loss is to radiation. And the SWR on a 1/2WL dipole standing wave antenna is quite high - in the neighborhood of 20:1. Just a quick question. What is the impedance at the centre of an infinitely long dipole (in free space)? Ian. -- |
