A modular filter system includes a wideband combiner, which includes an antenna connector and wideband filter connectors, and multiple filter modules. A first filter module includes a first connector configured to pass a first frequency band. The first filter module includes a combiner connector configured to pass the first frequency band, which is coupled to the combiner connector. The second filter module includes second, third, fourth, and fifth connectors configured to pass second, third, fourth, and fifth frequency bands, respectively. The second filter module further includes a combiner connector configured to pass the second, third, fourth, and fifth frequency bands, which are coupled to the combiner connector.
