Use one coaxial cable for TV and satellite with the Spaun SEW 121 F. The combiner brings together a terrestrial TV antenna signal and a satellite feed from an LNB or DiSEqC switch into one shared output, simplifying the cable run to the TV location.
The product has two inputs and three F connections in total. The terrestrial input covers 5–862 MHz, while the satellite input covers 950–2200 MHz. At the TV location, the signals are separated using a compatible TV/radio/SAT outlet or suitable signal separator.
With 1.5 dB satellite insertion loss and 1.5–2.5 dB terrestrial insertion loss, signal loss through the combiner is limited. Filtering provides more than 32 dB band rejection in both directions.
DC pass-through on the satellite path allows power to reach the satellite equipment. The specified DiSEqC and tone-control pass-through requires compatible components throughout the installation.
✅ Product Benefits
- TV and satellite over one coaxial cable.
- Two inputs and one shared output.
- Low insertion loss on both signal paths.
- More than 32 dB band rejection between TV and satellite.
- DC pass-through on the satellite path.
- Pass-through for DiSEqC and tone control.
- F connections for coaxial cables.
- Compact housing with mounting holes.
🎯 Ideal For
- Installations with both a TV antenna and satellite dish.
- TV locations using one shared coaxial cable run.
- Upgrading existing antenna cabling.
- Systems with TV/radio/SAT wall outlets.
- Satellite installations with an LNB or DiSEqC switch.
🔧 Connection and Operation
Connect the TV antenna signal to the Terr. input and the cable from the LNB or DiSEqC switch to the SAT input.
Connect the shared centre port to the coaxial cable running to the TV location. Separate the signals at the other end using a compatible TV/radio/SAT outlet or signal separator.
For satellite power and control to work, the entire satellite path must provide suitable DC and control-signal pass-through.
