Satellite multiswitch JULTEC JRM1712M — 9 inputs, 16 outputs, 35 dB decoupling

JULTEC JRM1712M is a satellite multiswitch with 9 inputs and 16 outputs designed for distributing satellite signals to multiple receivers in residential and small commercial multisystem installations. The unit provides 35 dB input decoupling to minimise interference between inputs, accepts 9 V control voltage on designated inputs, and draws approximately 300 mA of power. Housed in a compact metal enclosure measuring 211×144×54 mm, the multiswitch is intended for indoor or equipment-rack mounting where space is limited.

Advantages

The multiswitch combines high input isolation with a compact metal housing to reduce electromagnetic interference and ensure reliable signal distribution. Its nine-input configuration supports multiple polarization and band combinations from LNBs or distribution amplifiers while the 16 outputs allow connection of many receivers without additional splitting. Low power consumption and standard control voltage support integration with common satellite installations.

Suitable for

• Distribution of satellite signals to up to 16 receivers in homes or small apartment buildings
• Multisystem installations requiring several LNB inputs (polarizations and bands)
• Indoor mounting in equipment closets or small racks
• Installations where compact footprint and robust metal housing are preferred

Key specifications

• Number of inputs: 9
• Number of outputs: 16
• Input decoupling/isolation: 35 dB
• Control/input voltage: 9 V on designated inputs
• Power consumption: approximately 300 mA
• Housing material: metal
• Dimensions: 211 × 144 × 54 mm

How to use

Install the JULTEC JRM1712M in a dry, ventilated indoor location and secure it to a surface or equipment rack using appropriate fasteners. Connect up to nine satellite inputs (LNB outputs or upstream multiswitch feeds) to the corresponding input connectors, observing polarity and band/polarization assignments. Connect up to sixteen receivers to the output ports using coaxial cables of suitable quality and length. Provide the required control voltage where indicated and verify power and signal levels with a satellite meter or receiver diagnostics to ensure correct distribution and reception.

Recommendations

Use quality coaxial cable and connectors to maintain signal integrity, avoid routing cables near high-power electrical equipment, and keep cable lengths as short as practical. For installations with long cable runs or marginal signal levels, consider inline amplification or pre-amplified LNBs to compensate losses. Follow local regulations and safety practices when mounting and connecting the device.
