That's correct - it's charge acceleration and deceleration which causes
radiation. If you take a long wire and terminate it in its
characteristic impedance it will radiate - there doesn't need to be a
discontinuity at the end. Same for a terminated Rhombic.

This is incorrect and misleading. Whenever an AC current flows on a
wire, there is an accompanying and inseparable AC electromagnetic
field surrounding the wire. And the said AC field propagates in all
directions. It is as simple as that. No special conditions are needed,
and one doesn't have to do anything special in order to provoke
radiation. "Radiation" would be easier to comprehend if we stopped
calling it "radiation", and started calling it "disturbance
propagation", what it actually is. 73, Sinisa YT1NT, VE3EA
