The VHF elements on the ‘explorer C3’ are the telescopic elements. On the ‘explorer C2’ the VHF is the rear antenna that consists of 6 elements.
In the past there were a lot more VHF signals than are present currently. Over the years as new transmitters were installed the percentage of transmitters being UHF have greatly exceeded than that of the VHF.
Currently around 87% of the transmitters around Australia are UHF (Ultra high Frequency) the remaining are VHF. With the addition of digital services around Australia these percentages will remain somewhat the same. The older areas such as the capital cities will remain VHF even when the analogue signals are switched off. A decision by the government was made, I guess, to not force every one to change their existing antennas and so they squeezed the digital signals in between the old analogue signals thus maintaining the VHF range for television. Therefore the answer to the above question is ‘Yes’. At this stage VHF will still be required for some areas and therefore as the caravanners are always on the move they should have an antenna that functions in both areas of the spectrum.
