The Seebest SB-212SA1 is a precision-engineered 2-way satellite switch designed for users who need to toggle between two different LNB signals through a single receiver. Utilizing a standard 0/22KHz control signal, this switch allows your satellite receiver to automatically select between LNB-A and LNB-B, making it an essential component for multi-satellite home theater setups.
2-In 1-Out Configuration: Connect two satellite LNBs to a single coaxial output for efficient signal management.
High-Frequency Performance: Optimized for the 950–2300MHz range, ensuring full compatibility with modern digital and high-definition satellite broadcasts.
0/22KHz Signal Control: Integrated switching logic responds instantly to pulse commands from your receiver to toggle between "ON" (LNB-A) and "OFF" (LNB-B) states.
Heavy-Duty Zinc Housing: Housed in a rugged, die-cast metal enclosure that provides superior shielding against electromagnetic interference (EMI).
Low Signal Loss Architecture: Designed to maintain signal purity and minimize insertion loss, preserving the strength of your satellite feed.
Integrated Mounting Tabs: Features built-in screw holes for secure, permanent installation to walls or equipment racks.
Multi-Satellite Viewing: Effortlessly switch between two different satellites (e.g., local and international feeds) on a single receiver.
Universal LNB Setups: Ideal for systems requiring a dedicated switch to manage dual-band LNB configurations.
Cable Management: Reduces the number of cables entering the home by combining two LNB feeds into one main line.
Model: Seebest SB-212SA1.
Control Signal: 0/22KHz.
Frequency Range: 950–2300MHz.
Input Ports: 2 x F-Type Female (LNB-A / LNB-B).
Output Port: 1 x F-Type Female (Receiver).
Does this require a separate power adapter?
No. Like most satellite switches, the SB-212SA1 is powered directly through the coaxial cable by the DC voltage supplied from your satellite receiver.
Is this the same as a DiSEqC switch?
While it serves a similar purpose, this unit uses a 0/22KHz pulse tone rather than the DiSEqC protocol. Check your receiver's antenna settings to ensure it supports 22KHz switching.
Can I use this for my local cable TV?
This switch is specifically designed for the higher frequency ranges used by Satellite (LNB) equipment (950MHz+). It is not recommended for standard terrestrial or cable TV splitters which typically operate below 900MHz.
