Im reading the ARRL 19th edition Antenna Book, chapter 2 of antenna fundamentals.
Under the section of "Impedance of a Center-Fed Dipole" it tells me that:
A center feed dipole can be any length electrically, as long as it is configured in a symmetrical fashion with two equal-length legs.
my question is what is the books meaning of "any electrical length". I suppose I am asking what defines "electrical length".
Is the electrical length just the physical length of the wire based on wavelength and frequency?
Please provide an example if you can.
