Question B-006-010-011

What is the main reason why so many VHF base and mobile antennas are 5/8 of a wavelength?

Correct Answer

The angle of radiation is low

Explanation

Compared to a 1/4 wave, the 5/8 wave antenna directs more energy towards the horizon, which is desirable for terrestrial VHF communication, resulting in gain.
