Cecil's antennas may be lossless,
Even more amazing is that they are linear transmission lines.
In spite of W7EL's assertions that antennas generate
nonsinusoidal waveforms, they indeed are linear and bear a
striking resemblence to a lossy transmission line. Why do
you think they are called standing wave antennas?
Take a look at page 18 of Balanis' "Antenna Theory", 2nd
edition, Figure 1.15. He shows how to turn a transmission
line into an dipole with exactly the same standing wave
current distribution before and after.
