My experience with the LeadTek cards (I have had two different models) 
is that they are inferior to both the ASUS and AverMedia devices that I 
currently use.
Each time the Coax is split, signal quality is reduced.    You could try 
plugging the Tuner card directly into the wall socket (without the 
splitter) and try tuning that way, (or check your tv plugged directly 
into the wall)

Jaycar sell a DTV Signal Meter 
http://www.jaycar.com.au/productView.asp?ID=LT3332, but I would be more 
inclined to go straight for 
http://www.jaycar.com.au/productView.asp?ID=LT3255 if you have access to 
the aerial, otherwise http://www.jaycar.com.au/productView.asp?ID=LT3287
