Hmm, i haven't heard anything about Fortec in a long time. One of my friends has one of those, and they are just like Pansats. Never heard of a "halfpanel file", but if you go on google and type it out i bet you will find something.
FORTEC LU AFTER MARCH 04,FULL PANEL=TYPE 2 FORTEC LU=Pansat 2500a type 2 The shaded part that you get lights through is the panel if it covers the left half area of the box is a half panel.If it has the shade on the left and right then is full panel.
