Abstract
Abstract A non-directional signal combiner including a common ground plane, first and second coaxial cable connectors and a sum port. Each of the connectors has an inner conductor and an outer conductor, with the outer conductors connected to the common ground plane. The combiner also includes first and second coaxial cables, each having inner and outer conductors. The inner conductor of the first coaxial cable extends between the inner conductor of the first connector and the sum port, while the inner conductor of the second coaxial cable extends between the inner conductor of the second connector and the sum port. Each of the first and the second coaxial cables are wound into coils.
