What is a dipole and balun?
A. The cable is connected to the dipole section of the aerial. This is where the TV signal is received and where the coaxial cable is connected. The balun (balanced to unbalanced converter) is the small printed circuit that is located in the dipole plastic housing and is used to match the dipole to the coaxial cable. This has the effect of maximizing the signal transfer from the aerial to the cable whilst minimizing the effects of impulse noise interference. something you really need to avoid!.
