The height of a VHF radio antenna is important because VHF is considered a “line-of-sight” communication an antenna can be made more broadband by increasing the volume it occupies. Hence, a dipole antenna can be made more broadband by increasing the radius A of the dipole. the fatter the dipole gets the lower the resonant frequency becomes. In other words, if an antenna is to resonate at 100 MHz, the resonant length decreases as the dipole gets ... Re: VHF Radio Antenna Length The bottom line with a VHF signal is that it is basically "Line of sight" if the antennas can't see each other, communication will be spotty to say the least.
