Quelle est la puissance apparente rayonnée d'un émetteur si la puissance de sortie de l'émetteur est de 200 watts, les pertes dans la ligne de transmission de 5 watts et le gain de l'antenne de 3 dBd?

Why

A gain of 3 dBd means the antenna concentrates the signal to produce twice the power in the strongest direction compared to a standard dipole. The full explanation — and one for every question — is in Pro.
