Gain antennas for mobile application

Discussion covers the development and testing of a reference antenna to provide meaningful gain figures for measuring mobile antennas in the 150 and 450 mc bands. Gain data and patterns are shown for various designs of mobile antennas from comprehensive testing. Relations are established between a one-quarter wavelength whip and a one-half wavelength dipole. General and specific conclusions are stated on mobile gain antennas and their application.
