A radio frequency network, comprises a first common node connected to a common input or output port, a second common node, and at least three identical branches therebetween, each branch comprising a first branch node, to which is connected a balance load, and a second branch node spaced therefrom and connected to a branch output or input port, the network being dimensioned and arranged such that an r.f. signal of a specific frequency input at the common input port is divided equally between all the branch output ports, and a plurality of identical r.f. signals of the specific frequency applied in phase to all the branch input ports appear combined at the common output port.
