True. You can include Terman among them.
Terman discusses antenna current distribution on page 866 of his 1955
edition:
"Under most circumstances the losses are sufficiently low and the ratio
of wire length to diameter sufficiently great so that to a first
approximation the current distribution can be taken as that for a line
with zero losses; it then has the characteristics discussed in Sec,
4-5."
Sec.4-5 is found on page 95 and is titled: "The Effect of Attenuation on
Voltage and Current Distribution - Lossless Lines".
Sec. 4-5 is in Terman`s chapter on Transmission lines. Obviously an
open-circuit antenna has the same current distribution as an
open-circuit transmission line, and for the same reason.
