With a design length approximately 0.95 times that of a standard half-wave ...Are you tired of paying hefty cable bills for channels you never watch? Are you looking for a more affordable alternative to access local TV channels? If so, then an antenna might ... This is consistent with the fact that it is a half-wave dipole antenna. The reason it’s not exactly half wavelength (35 cm in this case) is because of the end effect* and a resulting multiplication by 0.95. 35*0.95 = 33 cm (which is what the computation gives us) The actual formula for length (L) in feet of the half wave dipole is: L = 492 / f. A “link dipole” (or “linked dipole”) is a simple way to permit one antenna to be used on multiple bands.
