WIFI Antenna Output Thru Coax

Direct broadcast satellite dishes and over-the-air HDTV antennas require 75 Ohm Coaxial Cable to ensure that all of the digital channels transfer down the cable with the lowest loss and distortion possible. so your satellite cable is the wrong Impedance for wifi routers it should be 50 ohm cable and connectors or a mismatch and signal loss is the result. one crucial point in regards to coaxial cables. The Impedance of the various devices being connected as well as the Coaxial Cable itself must match. So if you are, for instance, connecting a 75 Ohm connection to the coaxial cable must also be 75 Ohm AND the connectors on the coaxial cable must be 75 Ohm in Impedance. Every single time you have a mismatch in impedance, say between a 50 Ohm Coaxial Cable and a 75 Ohm Coaxial Connector a standing wave develops. A standing wave is a signal reflection that is essentially wasted. Every time a 50 and 75 Ohm Impedance mismatch occurs, about 5% of the signal is lost. These losses add up and can eventually degrade the signal to the point that it is unrecoverable or distorted. not saying it will not work at all but all wifi antenna cables should always be as short as possible or the correct cable used for the length you are extending it or huge signal loss is the result. you could try it but don't spend a lot doing it.
