In the problem posed, the current is also uniformly distributed along

familiar with and what we might do with it.

Reg, in the real world, an antenna has radiation losses so
the current decays along its length. Is there any formula
that includes an attenuation factor for a traveling wave
antenna? It would be akin to the attenuation factor for
a transmission line but presumably higher.

I have estimated that, for a 1/2WL dipole, the reflected
voltage and current have dropped by approximately 10% below
the forward voltage and current during the round trip to the
ends of the antenna and back.
