It is difficult to design a single antenna to receive such a wide wavelength range, and there is an octave gap from 216 to 470 MHz between the VHF and UHF frequencies. So traditionally, separate antennas (outdoor antennas with separate sets of elements on a single support boom) have been used to receive the VHF and UHF channels. [6]
The development of interest in TV-FM DX as a hobby can arise after more distant signals are either intentionally or accidentally discovered, leading to a serious interest in improving the listener's antenna and receiving installation for the purpose of actively seeking long-range television and radio reception.
VHF is the first band at which wavelengths are small enough that efficient transmitting antennas are short enough to mount on vehicles and handheld devices, a quarter wave whip antenna at VHF frequencies is 25 cm to 2.5 meter (10 inches to 8 feet) long.
Their impedance can be made relatively constant over a frequency range 4:1 or more, with the forward gain increasing at 6 dB per octave. Multiple rhombic antennas can be connected in an end-to-end fashion to form MUSA (Multiple Unit Steerable Antenna). MUSA arrays can receive long distance, short wave, horizontally polarized downcoming waves.

A three-element Yagi–Uda antenna used for long-distance communication in the shortwave bands by an amateur radio station. The longer reflector element ( left ), the driven element ( centre ), and the shorter director ( right ) each have a so-called trap (parallel LC circuit ) inserted along their conductors on each side, allowing the antenna ...
