The Inverto IDLB-QUDM22-MNOO3-8PP is a Monoblock Quad LNB designed for simultaneous reception from two satellite positions separated by approximately 3°. It combines two Universal LNBs and a DiSEqC switch in one unit, providing a neat installation without separate LNBs, a multi-feed holder or external switches.
Its four independent outputs can supply up to four separate satellite receivers or tuners. Each connected tuner can independently select either satellite position as well as its required channel, polarisation and frequency band.
The integrated DiSEqC 1.0 switch controls satellite selection. Satellite A is factory assigned to the eastern satellite position and Satellite B to the western position. Satellite A is the product’s default position.
The LNB is designed for satellite dishes measuring approximately 75–85 cm with an F/D ratio of 0.6. It provides a typical noise figure of 0.2 dB, good frequency stability and support for digital satellite television, DVB-S2 and HDTV.

🎯 Ideal For
Reception from two closely spaced satellite positions
Satellites separated by approximately 3°
Homes with up to four receivers or tuners
Four televisions with separate satellite receivers
Two Twin Tuner receivers
One receiver with up to four independent tuner inputs
Houses and small multi-user systems
Installations avoiding separate LNBs and external DiSEqC switches
DVB-S2 and HDTV reception
Satellite dishes measuring approximately 75–85 cm
🔧 Connection and Operation
The LNB has four equivalent F-outputs. Each output connects by a separate coaxial cable to a satellite receiver or tuner.
Every connected tuner can independently control:
Satellite-position selection through DiSEqC 1.0
Vertical or horizontal polarisation through the supply voltage
Low or high band through the 0/22 kHz signal
The standard configuration is:
These settings may have to be entered manually in the receiver’s antenna menu. Depending on the receiver, the ports may be identified as Port 1/2, A/B or AA/AB.
A Twin Tuner receiver normally requires two separate cables from the LNB for full independent operation. Four outputs therefore mean a maximum of four independent tuners, which does not always equal four physical receiver boxes.

Please note: This is a Quad Monoblock LNB, not a Quattro LNB. All four outputs are independent and can be connected directly to receivers or tuners.
🛰️ Installation and Dish Size
The Monoblock LNB is designed for satellite dishes measuring approximately 75–85 cm with an F/D ratio of 0.6. A dish of around 80–85 cm is normally recommended for optimum performance.
Reception from two satellites using a fixed Monoblock LNB is affected by:
The exact angular separation between the satellites
The installation location
The size and geometry of the satellite dish
The design of the LNB holder
Which satellite is positioned at the main focus
Correct elevation, azimuth and skew adjustment
Verify that the required satellite positions match the product’s fixed 3° geometry before installation.
