LNB AB-COM Mascom Monoblock 4.3 Single MC M4-S01/S02/S03 Universal — single LNB for 4.3° motor or twin-dish setups

LNB AB-COM Mascom Monoblock 4.3 Single MC M4-S01/S02/S03 Universal is a single-output monoblock LNB precisely optimized for receiving satellites with 4.3° spacing, specifically tuned for Astra3 (23.5°) and Astra1 (19.2°). It provides low noise performance and a compact design suitable for motorised installations or paired-dish setups that require a monoblock interface and one coaxial output.

Advantages

The monoblock offers a low noise figure of 0.3 dB and a minimum gain of 50 dB, ensuring stable reception of DVB-S/DVB-S2 signals. It features a 23 mm feedhorn with a 40 mm adapter included in the package, a rubber grommet for connector protection and compact dimensions that facilitate installation on motors or dual-dish mounts. The converter uses fixed 4.3° spacing (exactly 4.3°) between inputs, not a variable 4°–6° device.

Suitable for

• Home satellite TV reception targeting Astra3 (23.5°) and Astra1 (19.2°)
• Motorised satellite dish setups with 4.3° monoblock interface
• Paired-dish (twin-dish) installations using a single LNB output

How to use

Mount the monoblock LNB on a compatible motorised arm or dual-dish bracket with the correct 4.3° spacing orientation so the two focal points align with Astra3 and Astra1. Connect the single coaxial cable from the LNB output to your satellite receiver input. Configure your receiver to scan the appropriate satellite positions (23.5° and 19.2°) and set the correct L.O. frequency if required. Ensure the rubber grommet protects the connector from moisture and tighten all fittings securely.

Usage recommendations

Use this monoblock on dishes and motor mounts configured for 4.3° spacing; do not assume it provides adjustable 4°–6° spacing. For best results, verify dish alignment and cabling, and keep the connector grommet in place to prevent water ingress.
