ALFA ARS-AS01 is a magnetic mount antenna base with RP-SMA connector. It comes with antenna extension cable built into the base (1m). This is a great way to get more signal on your ALFA Network wireless receiver, such as ALFA models AWUS036H or AWUS036NH. Simply connect this magnetic base to your ALFA adapter’s RP-SMA port with the built-in cable and then connect the ALFA antenna you already own to the top of the magnetic mount base. Now you can place your antenna up to 1m away from the adapter for improved reception.
