I currently have great reception for all of my OTA stations, but would like to distribute the signal to 5 more more TV's and HD tuner cards on PC's. I use a CM 7777 preamp from the antennas (attic install) to my AV hub in the basement (about 70')and would like to use some sort of powered splitter before i sent the signal out to all of the devices. The only one i have found with a quick google search is the CM 3418 http://www.solidsignal.com/pview.asp?p=CM3418
Any reason why this would not work? My stations range from 42 miles to 68.
