What is an advantage of a 5/8-wavelength whip antenna for VHF or UHF mobile service compared to a 1/4-wave antenna?

توضیح

A 5/8-wavelength whip concentrates more of its radiation at a low angle toward the horizon than a quarter-wave whip, which gives roughly 3 dB of gain for terrestrial contacts. It is not resonant on its own, so it needs a matching network and does not have inherently lower SWR.
