Does the shape of the antennae matter in regards to the wave length of the radio signal?
I saw somewhere that radio antennae have their rungs (I’m thinking of a ladder style antennae) spaced to match the length of the radio wave. So a higher frequency radio wave might have the rungs of the antennae spaced closer together (not sure if this is the right terminology, but picture old school TV antennae with a central pillar and “rungs” to either side).
Were old school antennae designed to have similar spacing as the actual length of the radio wave, or some multiple of the wave? How is this process interpreted and is this even a proper way to think of a radio receiver? Or is this just wrong. It seems to me that the wave lengths wouldn’t be more than a millimeter long.
