Satellite LNB Telkom-Telmor SC 40 Quad LNB 950–2150 MHz 55–65 dB

Telkom-Telmor SC 40 Quad LNB is a satellite low-noise block converter designed for receiving Ku-band satellite broadcasts and distributing the downconverted signal to up to four tuners or receivers. Covering the 950–2150 MHz IF range, this quad-output LNB supports multiswitch and multiroom installations where a single dish feeds multiple set-top boxes or satellite receivers. The device features gain in the range of 55–65 dB to ensure adequate signal amplification for domestic reception scenarios.

Advantages

The SC 40 Quad LNB offers four independent outputs allowing simultaneous connection of multiple receivers without the need for additional splitters. Its wide IF bandwidth of 950–2150 MHz makes it compatible with standard Ku-band systems and most multiswitch configurations. The specified gain of 55–65 dB provides a balance between sensitivity and stability, suitable for typical home installations. The unit is compact and intended for straightforward mounting on standard satellite dishes.

Suitable for

• Home multiswitch systems feeding several receivers
• Small apartments with multiple tuners
• Single-dish multiroom satellite installations
• Replacement of a damaged or worn quad LNB on Ku-band dishes

Key specifications

• Type: Quad-output LNB for Ku-band reception
• IF frequency range: 950–2150 MHz
• Gain: 55–65 dB
• Number of outputs: 4 independent outputs
• Application: Multi-receiver and multiswitch setups

How to use

Install the LNB at the focal point of a compatible Ku-band satellite dish following the dish manufacturer’s alignment procedure to achieve proper azimuth and elevation. Securely fasten the LNB to the feed arm with appropriate clamps, then connect coaxial cables from each of the four outputs to satellite receivers or to the inputs of a multiswitch. Power is supplied through the coax from connected receivers or a multiswitch; ensure receivers and cabling meet recommended specifications for satellite installations. After physical installation, fine-tune dish alignment while monitoring signal strength and quality on the receiver until optimal reception is achieved.

Usage recommendations

Use high-quality, low-loss coaxial cables and weatherproof F-type connectors to preserve signal integrity. If feeding more than four tuners, employ a compatible multiswitch and ensure LNB compatibility. Periodically inspect the LNB and connections for corrosion or water ingress, and reseal connectors with suitable tape or boots where exposed to weather.
