After UHF transmissions started in the early 1960s there was a market for combined UHF/VHF TV aerials. This Jaybeam example has a single dipole for Band I vertical, a five element Band III vertical array that has a Band III halfwave linked at the ends to the Band I dipole. The UHF section is electrically separate with its own connection box and downlead. These arrays needed the Band III and UHF transmitters to have opposite polarities and be in the same direction.
