1. Main technical objectives

By improving performance

First and foremost, this very important characteristic embodies the ratio of the power delivered to the antenna (P_a) and the total power consumed from the network (P_tr). The overall efficiency η_g incorporates all consumption, fans, hydraulic pumps and all losses, including power supply transformer losses : $η_{g} = \frac{P_{a}}{P_{tr}}$

Solid-state emitters deliver very high efficiencies, from 88% measured at medium-wave, to 90% at long-wave. These...
