I got a Hipix card a week ago and I just got to installing it today (Yes, I'm lazy ) and I managed to set it up without a hitch. The thing that shocked me the most is that it's able to lock on to a signal at only 46% strength!! I had been pulling my hair out trying to get a stable signal on my HD-100 STB using Attenuators, FM Traps, Amplifiers, and I just couldn't get a stable signal at 90% (reported by the STB). I just hooked up my Silver Sensor Antenna straight up the card with no attachments and it got a signal strength of about 46% but it's able to deliver me a 100% stable picture with no dropouts on all 3 ATSC channels that are available! I'm very pleased. However this was just regular NTSC being fed through the ATSC channels, and I did have audio muted, does watching an HD broadcast put extra strain on an Antenna?
