There's no confusion. Terminated rhombics and Beverages are
traveling-wave antennas. Their currents are primarily:

I(x,t) = Io*cos(kx-wt)

A 1/2WL dipole is a standing-wave antenna. It's current is
primarily:

I(x,t) = Io*cos(kx)*cos(wt)

There's no confusion except in your mind.

What is the common reference point of x,t? In other words, when both x and t are zero, where on the antenna is the zero location?
