There's comparisons and choices to be made.
The OLD Pansat 3500 DVB-S receiver can operate a servo feedhorn for polarity. But not much would be available as most has switched to DVB-S2. (I've relegated my Pansat 3500 to one satellite/one transponder for it's 'content')
Their newest, the Pansat 9500HDX DVB-S2, receiver will also operate it. (still need something else to move the dish)
The Titanium Satellite ASC-1 actuator controller will also operate a servo feedhorn. (as well as power the actuator using just about any receiver- servo polarity and dish position 'in one')
That opens up the choices for receiver as any modern FTA box could operate the ASC-1.
A new C Band LNBF replacing the servo feedhorn means a V-box could move the dish and the receiver selects polarity via LNB voltage. (Standard method)
