I thought aerial dimensions went to scale with the wavelength
I know an indoor FM radio aerial as a squashed loop is 5 foot long
Long wave aerials used to be the length of the garden
405 aerial was bigger than 625 aerial etc

Yes and no. *Some* aerial designs have to be a particular fraction of
the wavelength, but you will find that a LW and MW radio works just
fine with a 6 inch ferrite rod aerial instead of a 300 meter long
metre
dipole.


sorry, one of the ones that annoys me unreasonably

Yup, me too, because I *always* get it wrong :-}
