The MW550P is an active preselector and antenna matching unit for AM broadcast and 160 m reception. The MW550P will match any antenna (eg. random wire, beverage etc.) to 50 Ohms across the broadcast band. The selectivity can be varied by adjusting the antenna coupling and a 4 kHz bandwidth is achievable.
