The MRF-300 is addressable via 15 separate station ID's and six addressable IR outputs. This allows up to 90 components (or zones on a multi zone system) to be simultaneously controlled in one household via multiple base stations, more than enough for even the largest multi-zone systems. The MRF-300 includes one RFX-150 antenna module. The RFX-150 is separately mounted (in an interference free location) and connected to the MRF-300 base station by a three conductor cable up to 80 metres away. By combining additional RFX-150 antenna modules in parallel using a three conductor wire connected to a centrally located MRF-300 RF base station.
