CHARACTERISTICS OF VERY HIGH FREQUENCY AND ULTRA HIGH FREQUENCY DIRECTIONAL ANTENNAS AND THEIR MEASUREMENT (EIGENSCHAFTEN VON VHF UND UHF RICHTANTENNEN UND IHRE MESSUNG)

Abstract

Certain phenomena associated with the radiation characteristics of directional antennas, of particular practical importance in communications engineering, are carefully defined and dealt with in detail. In the measurement of the radiation characteristics, only the coaxial system (60-ohm-coaxial cable) is used, as this gives the smallest error, and in the measurement of the directional diagram only the normalized diagram is taken, as the normalized representation is generally valid.
