Universal Ku Band Quattro LNBF - 4 Output High Gain Low Noise for VSAT
A Ku-Band Quattro Low-Noise Block Downconverter (LNBF) engineered for Very Small Aperture Terminal (VSAT) systems. This unit features four independent, phase-stabilized output ports, each dedicated to a specific polarization (Horizontal High/Low, Vertical High/Low), enabling simultaneous multi-receiver or multi-frequency operation within the 10.7-12.75 GHz spectrum.

What is a Quad LNB?
A quad LNB is engineered to serve multiple tuners directly without the need for additional equipment like a multiswitch.
  • Four Independent Outputs: The defining feature of a quad LNB is its four independent outputs. Each output is capable of driving a separate tuner, enabling direct connection to up to four satellite receivers.
  • Full Ku-Band Coverage: In a quad LNB setup, each output provides signals from the entire Ku band. This means that each tuner connected to a quad LNB has access to all available satellite channels without restriction.
  • Direct Tuner Connection: Quad LNBs are commonly used in installations where each satellite receiver requires its own dedicated connection to the LNB. This setup is prevalent in residential settings where viewers prefer individual access to satellite channels.

What is a Quattro LNB?
On the other hand, a quattro LNB serves a distinct purpose in shared dish distribution systems.
  • Designed for Multiswitch Integration: Unlike quad LNBs, quattro LNBs are specifically intended for use with multiswitches in shared dish distribution setups. These multiswitches facilitate the distribution of satellite signals to multiple receivers or users in shared environments like apartment buildings or commercial properties.
  • Four Outputs, Quarter Band Signals: Similar to quad LNBs, quattro LNBs also feature four outputs. However, each output provides only a quarter of the Ku band signals rather than the entire spectrum.
  • Signal Division: The signals provided by each output of a quattro LNB are typically divided based on polarization and frequency bands. This division ensures that each output delivers a specific subset of satellite signals, facilitating efficient distribution in shared systems.

What is the Difference Between Quattro LNB and Quad LNB?
Although both quad and quattro LNBs offer four outputs, their functionality and applications differ significantly. A quad LNB is suitable for direct connection to multiple tuners, providing access to the entire Ku band for individual receivers. Conversely, a quattro LNB is tailored for integration with multiswitches, distributing quarter-band signals to multiple users in shared dish distribution systems. Understanding these differences is crucial for selecting the appropriate LNB for a specific satellite TV installation scenario.
Practical Selection Guide
Choose a QUAD LNB when:
  • You are installing a standard single-home system
  • You need to feed 1 to 4 satellite tuners/receivers directly
  • Examples:
    • House with 4 TVs, each with its own receiver
    • House with 1x dual-tuner PVR (needs 2 cables) + 2x basic receivers
    • Simple setup where each cable runs directly from dish to receiver
Choose a QUATTRO LNB when:
  • You are installing a communal distribution system (apartment block, hotel, etc.)
  • You need to feed a multiswitch that will distribute signals to many receivers (16, 24, 48+)
  • Examples:
    • 12-flat apartment building with a central dish feeding all apartments
    • Hospital with satellite TV in each room
    • Any installation where the number of outputs needed exceeds what a Quad/Octo can provide directly
