## Summary description

AB-COM LNB Monoblock 4.3 Twin MC M4-T03 is a dual-output low-noise block downconverter designed for satellite reception. The monoblock format integrates two LNBs for receiving signals from adjacent satellites; twin outputs allow connection of two receivers or a dual-tuner PVR. Suitable for home satellite TV installations where compact dual-satellite reception is required.

## Long description

LNB AB-COM Monoblock 4.3 Twin MC M4-T03 Dual Output Low Noise is a compact monoblock converter designed for simultaneous reception from two closely spaced satellites with 4.3° separation (Astra 19°E and Astra 3A). It integrates two fullband LNBs with a built-in DiSEqC switch and provides two independent outputs for connecting two receivers or a dual-tuner PVR. The device features a low noise figure of 0.3 dB for improved signal quality in home satellite TV installations.
Advantages
The monoblock design combines two LNBs in a single housing for easy installation on a single dish, reducing alignment work. Fullband operation supports a wide frequency range for common DVB-S/DVB-S2 broadcasts. The integrated DiSEqC switch allows automatic switching between the two satellite positions without additional external switches. Twin outputs enable connection of two separate receivers or a PVR with two tuners while maintaining a low noise figure of 0.3 dB.
Suitable for
 Home satellite TV reception from Astra 19°E and Astra 3A (4.3° separation)
 Installations requiring two independent receiver connections or a dual-tuner PVR
 Compact setups where space or dish size limits adding separate LNBs

How to use
Mount the monoblock on the satellite dish feed arm according to the dish manufacturer’s alignment marks, ensuring the correct orientation for 4.3° satellite spacing. Connect each of the two coaxial outputs to the corresponding satellite receivers or to the two tuner inputs of a PVR. Configure the receivers to use DiSEqC switching to select between Astra 19°E and Astra 3A. Fine-tune dish alignment for optimal signal strength and quality using the receiver’s signal meter.
Usage recommendations
Use a properly sized and aligned dish compatible with 4.3° monoblock spacing; use quality coaxial cables and connectors to minimize signal loss. If signal levels are marginal, check cable integrity, weatherproof connections, and consider a larger dish. Ensure receivers support DiSEqC switching and fullband LNBs for correct operation.
