Off Center Fed Dipoles Folded dipole antenna basics. In its basic form the folded dipole antenna consists of a basic dipole with an added conductor connecting the two ends together to make a complete loop of wire or other conductor. As the ends appear to be folded back, the antenna is called a folded dipole. Antenna is 100% passive. No active circuit is involved.

The 80m Amateur Radio band is wide very wide. Covering 3500 to 4000 kHz, this band extends well beyond the normal resonant range of a single dipole antenna. Short of simply pressing “TUNE” on my rig’s internal antenna tuning system and living with the high SWRs, I really wanted to try something a bit more. The folded dipole has a slightly better SWR bandwidth than a conventional single wire dipole. In other words, a greater portion of the band is available at less than 1.5:1 SWR than with a single wire dipole. The act of folding the antenna transforms the input impedance to a higher value providing an easier match in some cases. Power is shared evenly between the two sections resulting in an increase in impedance, and current in each is reduced to half. With the same power applied to the antenna, the impedance is increased by a factor of 4.
