What is a Satellite Converter (LNB)?
A satellite converter, also known as an LNB (Low Noise Block), is an essential device mounted on a satellite dish arm. It captures signals from satellites, amplifies them, and converts high-frequency signals (10.7–12.75 GHz) into lower frequencies (950–2150 MHz) that your receiver can handle. LNBs support horizontal/vertical polarization and low/high bands.
Key Parameter: Noise figure – the lower, the better (0.1–0.3 dB recommended). Lower noise ensures stable HD/UHD signals even in adverse weather.

How to Recognize a Faulty Satellite Converter
A malfunctioning LNB can cause signal loss or interference. Watch for these signs:
- On-screen messages: “No Signal,” “LNB Short,” or “Check Antenna Installation.”
- Image/sound issues: Pixelation, freezing, audio pops, especially during rain or snow.
- Weather sensitivity: Signal drops despite correct antenna alignment.
- Physical damage: Cracks in casing, loose F-connectors, frayed cables.
Tip: Always check the cable and receiver first, then use a signal meter to confirm the LNB status.
How to Install and Align a Satellite Converter
Proper alignment is crucial for stable reception. Here’s a step-by-step guide:
- Mount the LNB on the dish arm and point it toward the satellite (e.g., Hot Bird 13°E for Poland).
- Set azimuth and elevation using an online calculator (e.g., satlex.de).
- Adjust skew/polarization angle (Poland: ~7–10° left from dish rear).
- Connect to tuner or signal meter and fine-tune until signal strength reaches 70–80% and quality 90–100%.
- Ensure clear line of sight – no obstacles like trees or buildings. Offset dishes tilt slightly downward.
Receiving Free-to-Air Satellite Channels
You can watch FTA (Free To Air) channels without subscriptions:
- Equipment: 60–80 cm satellite dish, LNB, FTA receiver (200–300 zł).
- Hot Bird 13°E: ~20 Polish FTA channels (TVP1, TVP2, TVP Sport, TV Trwam).
- Astra 19.2°E: Additional channels, totaling 600+ international channels.
- Tip: For terrestrial channels, add a DVB-T2 antenna for basic Polish channels like Polsat and TVN.
Satellite Converter Prices
- Single LNB: From 14–18 zł
- Twin LNB: 25–50 zł
- Quad LNB: 40–80 zł
- Unicable: 100–250 zł
- Average: ~116 zł, cheapest from 10 zł
Check online retailers like Allegro or Media Expert for the latest offers.
Professional Installation Costs
Hiring a technician varies depending on location and complexity:
- Antenna setup: 60–150 zł
- Balcony installation: 120–250 zł
- Roof installation: 150–250 zł
- Servicing/repair: 150–250 zł + materials
Prices exclude VAT; major cities may be higher.
Factors Affecting Signal Quality
A high-quality LNB significantly impacts signal reception. Poor LNBs may cause pixelation or signal loss during rain. High-performance models with low noise (0.1–0.3 dB) ensure HD/UHD stability. A larger dish (80–90 cm) also improves signal-to-noise ratio, especially in 4K setups.
Multi-Satellite Reception: Hot Bird and Astra
For receiving two satellites with a single dish:
- Monoblock LNBs: Combine Hot Bird 13°E and Astra 19.2°E
- LTC LXSAT403 Quad – 4 outputs, low noise
- Opticum Twin Robust – dual output
- Setup: Point dish to Hot Bird; Astra will be slightly offset (~right).
4K and UHD Satellite Converters
To enjoy 4K channels, choose LNBs with low noise and high gain:
- Inverto Single Premium: From 38 zł
- TechniSat Unix Gold Quad: Up to 80 zł, UHD compatible
- Opticum SCR Unicable: Multiroom setups, from 100 zł
Conclusion:
Choosing the right satellite converter depends on your number of tuners, desired resolution, and multi-satellite requirements. Always opt for low-noise, stable LNBs, and ensure proper alignment for optimal reception. With the right equipment and setup, you can enjoy crystal-clear HD and 4K channels across Europe.
