I dont know if it helps but for comparison here are the details of my 
Hauppauge WinTV Nova-T-500.

Packaging Description: WinTV Nova-T-500-HD
Package Bar Code: 7 85428 00298 9

This PCI card has 2 tuners -- but has onli 1 antenna input socket
lsusb id: ID 2040:9950 Hauppauge

The only issues I have had with this card have been
	The need to utrn on the LNA
	The need to cold restart to make sure the firmware loads.

I have clear line of sight path to Mt KauKau at a distance of approx 18 - 20 
Kms.

I have been able to run this card successfully on a pair of rabbit ears from 
this location.

Current Femon stats are:

Upstairs my TV which uses a homebrew folded dipole made from TV ribbon cable
taped to the back of the TV reports Signal strength 100 BER 0.

Hope this all helps.
