The Inverto Black Pro Twin Monoblock 3° is a high-quality Universal Monoblock LNB designed for simultaneous reception from two satellite positions separated by approximately 3°. It combines two Universal LNBs and integrated DiSEqC switching in one compact unit.
The LNB has two independent outputs and can supply two separate satellite receivers, two televisions with integrated satellite tuners or one Twin Tuner receiver. Both tuners can independently select the required satellite position, channel, polarisation and frequency band.
Its compact construction is particularly useful where the satellite positions are too close together for two conventional LNBs to be installed correctly beside each other. The product is designed for satellites separated by approximately 3° and for a satellite dish measuring around 80 cm.
The Monoblock LNB has a 23 mm mounting neck, and an adapter ring is included to facilitate installation in a compatible larger LNB holder.
With a typical noise figure of 0.2 dB, gain of 50–60 dB and good frequency stability, the model is optimised for digital satellite television, DVB-S2 and HDTV.

🔧 Connection and Operation
The LNB has two equivalent F-outputs. Each output connects by a separate coaxial cable to a receiver or tuner.
Every connected tuner can independently control:
Satellite position 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:
Satellite A is the default position. Depending on the receiver, the ports may also be identified as Port 1/2, A/B or AA/AB.
For a Twin Tuner receiver, both outputs must be connected using separate coaxial cables for full and independent functionality.
📡 Capacity and Functions
| Function | Capacity |
|---|
| Satellite positions | 2 |
| Satellite separation | Approximately 3° |
| Independent outputs | 2 |
| Directly connected tuners | Up to 2 |
| Single Tuner receivers | Up to 2 |
| Twin Tuner receivers | 1 using two cables |
| Satellite selection | Integrated DiSEqC 1.0 |
Please note: This is a Twin Monoblock LNB. Both outputs are independent and provide access to both satellite positions.
📡 Example Satellite Combinations
| Satellite combination | Separation | Requirement |
|---|
| Hotbird 13°E + Eutelsat 16°E | Approximately 3° | Compatible dish and accurate alignment |
| Eutelsat 16°E + Astra 19.2°E | Approximately 3.2° | Performance depends on dish and location |
| Other closely spaced satellites | Approximately 3° | Verify coverage and geometric compatibility |
Reception performance depends on satellite signal strength, installation location, dish size and geometry, and accurate antenna alignment.
🛰️ Mounting and Dish Size
The product has a 23 mm mounting neck and is supplied with an adapter ring. The adapter allows the LNB to be installed in a compatible larger holder.
For optimum reception, the following are recommended:
Satellite dish measuring approximately 75–85 cm
Approximately 80 cm under normal reception conditions
F/D ratio of around 0.6
Accurate elevation, azimuth and skew adjustment
Correct DiSEqC-port configuration on both receivers
Verify the diameter and design of the LNB holder before installation.
