The feed for 13v to the antenna was a ferite bead with 3 turns, it was attached

Have been using a sat passive splitter and most of my cables are using F
connectors so I'm thinking of modifying a DTV multi switch to provide 5 volts
instead of 13 volts on the LNB/antenna port. Antenna is a Trimble bullet II 5
volt antenna. The switch is active and I would ignore the 22Khz and
