[QUOTE="Channel Hopper, post: 5891, member: 175144"] Dear 2old Magnetic polarisers have gone the way of the 10GHz LNB and the Chapparal Monterey in the digital age, they are guaranteed to hinder the reception of MPEG signal if connected to the system Whilst the receiver has the ability to drive one, it is really a throwback to the old analogue days which the AD3000 can still receive.
