The disclosed embodiments include multi-channel communications filters, multi-channel communications systems, apparatuses that utilize a tunable multi-channel communications filter for antenna tuning, and methods to perform multi-channel communications filter tuning. A multi-channel communications filter includes a coupled inductor having a primary winding that is coupled to a power source, and magnetically coupled to one or more secondary windings. The multi-channel communications filter also includes a tuning bank formed from a first set of capacitors; and a first set of switches that are configured to adjust capacitance of the first set of capacitors to impede signals having a first frequency range from flowing through the multi-channel communications filter. The tuning bank and the first set of switches are coupled to the one or more secondary windings.
