best to use on twinhan board with ci

[hamguy2]

hi everyone, im chasing a version of my theatre or whatever else works with these .i have a twinhan sat pci card that excepts an irdeto cam whatever.i noticed on the square silver box which i think maybe the tuner there is 2 connections next to each other but only 1 f connection is ebabled and that by a little patch cord that runs from the tuner to the metal bit sticks out and it has a sat connection for your dish or diseq switch to plug in.i was wondering what the other connection on the tuners about but theres no little patchlead connected to it. its also a sat f socket its just got 2 instead of just the single sockets ive seen,thanks hamguy2 nsw .
