Satellite multiswitch JULTEC JRM1708M — 17 inputs, 8 outputs, 35 dB decoupling, 9 V

JULTEC JRM1708M is a satellite multiswitch designed to distribute satellite and terrestrial signals from multiple LNBs to several receivers. With 17 inputs and 8 independent outputs, the unit supports multi-room satellite installations and cascaded system architectures, offering input decoupling of 35 dB and a 9 V input voltage for connected equipment. The compact housing (211×144×54 mm) and 300 mA power consumption make it suitable for mounting in communication cabinets and distribution points.

Advantages

The multiswitch offers high input isolation of 35 dB to minimise signal interference between inputs and maintain stable reception across all outputs. Its 17-input configuration accommodates multiple LNBs or combined satellite and terrestrial inputs, while eight outputs provide distribution to several receivers or further cascade stages. The device's moderate power consumption and compact dimensions allow flexible placement in residential or small commercial installations.

Suitable for

• Multi-room satellite TV distribution in apartments and houses
• Cascaded multiswitch systems for expanded receiver counts
• Installations combining multiple LNBs or polarisation/band feeds
• Small commercial sites requiring several independent satellite outputs

Key specifications

• Inputs: 17 signal inputs for satellite and/or terrestrial sources
• Outputs: 8 independent output ports for receivers or cascade links
• Input decoupling (isolation): 35 dB to reduce cross-talk between inputs
• Input voltage: 9 V supply for connected LNBs or control signals
• Power consumption: 300 mA
• Dimensions: 211 × 144 × 54 mm (W × D × H)

How to use

Mount the multiswitch in a dry, ventilated location near the distribution point. Connect satellite LNB feeds and any terrestrial inputs to the appropriate input ports, taking care to use correctly labelled cables and suitable F-type connectors. Supply power to the unit according to the installation instructions and verify that the connected receivers are configured for the corresponding satellite feeds. When cascading devices, use the designated cascade outputs and ensure each stage is powered and terminated as required to maintain signal levels.

Recommendations

Use high-quality coaxial cables and professional F-type connectors to preserve signal integrity. Verify cable lengths and consider using amplification or attenuation where necessary to balance signal levels across long runs. During installation, test each output with a compatible receiver or spectrum meter to confirm proper signal distribution and adjust cascade configurations as needed.
