Yes and no. *Some* aerial designs have to be a particular fraction of

fine with a 6 inch ferrite rod aerial instead of a 300 meter long
dipole.

Well, if the signal strength is high enough, no aerial at all will
suffice. Just pickup on the PCB. Indeed, if you are close to a TV
transmitter it's common for it to swamp wanted signals causing patterning
etc on the picture. But that doesn't negate proper aerial design for the
majority.
