[QUOTE="Robbo, post: 597677, member: 256551"] Impedance matching. The source expects to see a 75 ohm load. A splitter achieves this using the circuitry inside. Sticking on two 75 ohm loads on in parallel would cause a mismatch causing signal loss and possibly degradation on some frequencies. In any case, for combining Terrestrial and satellite, you would not use combiner, you would use diplexer, as the diplexer multiplexes the two signals and is more efficient. [/QUOTE]
