The disclosed embodiments provide a plurality of antennas that can be interconnected with each other and with a central receiver in a self-assembling manner, such that antennas can be added, removed, and replaced with minimal configuration. Each antenna comprises an antenna feed circuit, an input connector, and an output connector. Each of the antennas may be configured to assign a first set of signal channels at its output connector to a second set of signal channels at its input connector (or vice versa) according to a predetermined or dynamically determined mapping. Each antenna may be further configured to assign a signal channel at its input connector to the signal it receives at its antenna feed circuitry. By sharing the same configuration for mapping signal channels between the antennas' input and output connectors and feed circuitry, the antennas can be added or removed in a sequence of antennas using simple cable connections and without having to rewire the connections at the central receiver.
