Spinner Coaxial directional coupler 2 probes
Directional couplers are used to couple a small amount of the RF signal from a coaxial line or a waveguide run. Directional couplers consist of a main line, i.e. the actual power transmission line, and at least one secondary line, where the small part of the coupled forward or returning power flows. Forward and returning power are coupled separately.
