Default Re: Is there a proper way to use a telescopic aerial on a portable FM radio?

The whip antenna is referred as a "dipole" that the ground plate acts like a mirror reflecting the image of the vertical monopole. I would have thought the efficency of antenna is poor if n is not an integer and less than 1:

antenna length = n x wavelength/4
