Isn't the uplink via a phone line when you have satellite service? In this sense, you would perhaps benefit from a tried solution from another satellite user instead of the above product that seems to be more tailored toward bidirectional cable services.
FWIW, there's a great forum I've used to assist friends & family when I've had problems troubleshooting bad installs & service problems I couldn't fix on my own. http://satelliteguys.us
There will likely be more than one solution posted in their user forums you could try.
I?m looking to boost the signal from my Direct TV multiswitch to one of the receivers. If have two other coax lines from the multiswitch to two receivers that work perfectly. I?m just having issues with a third coax line that doesn?t carry a good enough signal (I get sound but the image is stuck). I tired an inline amplifier and it didn?t work. Will a powered amplifier work better? I saw this thing on Amazon but does it only work for cable TV and not Direct TV / Satellite TV? http://www.amazon.com/Motorola-Booster-484095-001-00-Bi-Directional-Amplifier/dp/B000066E6Y
