But is the another phenomenon. The Luxembourg effect.
The dipole radiate the doubled frequency.

Ah yes - the famous "is it a dipole or is it a dipole?" test. Of course,
it wouldn't discriminate between a dipole and a yagi (staggered or
phased?)

Luxembourg effect? Harmonics?

Harmonics are in string, plate, piano box etc.

Pendelum and LC circuit have the one frequency only.

LW from the dipole mast were (and are) received on MW receivers at exactly
doubled frequency.

Yup. Harmonics. The Luxembourg effect was cross-modulation. I'd completely
forgotten about it.

Was it a dipole or was it a dipole?
