Amplitude Characteristics and Directional Patterns

Abstract

First, the feeder and the antenna are a load in relation to the radio transmitter. Therefore, the value of this load should be such that an effective mode of operation of the radio transmitter is ensured. Secondly, the range of the radio communication line, among other factors, depends on the value of the radiated antenna power. In some cases, the power at the antenna input is so high that there is a real threat of mechanical destruction of individual elements of the antenna or feeder due to electrical breakdown or thermal overheating.
