A tap device for use in broadband communications systems includes a circuit board mounted on a cover plate assembly which is removably connected to a base housing. The circuit board includes an RF signal coupling element and an RF signal splitting element. The output of the RF signal coupling element and the input to the RF signal splitting element are each connected to a separate female receptacle positioned on the circuit board. The female receptacles are designed to receive an intermediate circuit which, when inserted into the female receptacles, is electrically connected between the RF signal coupling element output and the RF signal splitting element input. The intermediate circuit may consist of a short circuit feedthrough, or a plug-in fixed or variable degree attenuator. The intermediate circuit may also include a duplex filter and plug-in attenuator arrangement for attenuating higher frequency RF signals provided from a source which pass through the tap device to a load connected to the tap device outlet independently of lower frequency RF signals provided from a load which pass through the tap device for delivery to the source.
