You have 3 cards in a row???

Sounds that the signal level is too low.

Maybe you can test an external 1:3 or 1:4 "splitter" with lower
damping? (those "db" values). See Reichelt Elektronik.

              Sat-Splitter (DC pass thru!)

Don't cascade splitters. (If you can't get a 1:3 use a 1:4
and terminate the unused plug with 75 Ohm (or leave open...;-))
Maybe you need an amplifier (Conrad has a nice "in line" Sat-Amp)
(i need one: Without splitter it's ok, but with splitter
it is not good working. Similar to your problem.)
Place an amplifier as near as possible to the antenna.
(Not more than 30m away, anyway ;-))

Keep cables short.
Use good cables.
