| Challenge | How This LNBF Solves It |
|---|---|
| Quad independent output design – four receivers tune independently. Living room watches news, bedroom watches sports, study watches documentaries, kids' room watches cartoons – no interference. | |
| Four outputs can connect 2 dual-tuner PVRs – supports simultaneous recording of different polarizations. Never miss精彩 content. | |
| One dish serves four rooms – no need for separate dishes per room. Dramatically reduces installation costs. | |
| No external switches needed – four output ports connect directly to receivers. Saves equipment cost, reduces signal loss. | |
| Noise figure as low as 0.5dB (Typ.) – industry-leading performance. Excellent weak signal reception for clear picture quality. | |
| Wide temperature design (-30℃~+60℃) with only ±0.75MHz drift – stable signal in heat or cold. | |
| O-ring sealed waterproof design – effectively prevents rain and moisture ingress. Reliable operation in all weather conditions. |
| Traditional Solution | Quad LNBF Solution |
|---|---|
| Requires external multiple switches (DiSEqC) and splitters | No external switches needed – four outputs connect directly to receivers |
| Multiple devices introduce cumulative signal loss (3-5dB) | No additional loss – higher signal quality |
| More components = more potential failure points, complex maintenance | Fewer components – higher reliability, simpler maintenance |
| Requires complex wiring planning and professional installation | Simple installation – easy for standard installers |
| Multiple receivers may interfere with each other | Independent tuning – ≥20dB isolation, no interference |
| Higher cost (switches + splitters + more cables) | Lower cost – all-in-one solution |
| Application | Description |
|---|---|
| One dish serves living room, master bedroom, guest room, and study – family members watch their favorite programs | |
| Connect 2 dual-tuner PVRs – supports simultaneous recording of multiple channels. Never miss wonderful content | |

Q: What is a Quad LNBF?
A: A Quad LNBF has four independent receiving channels sharing a single feedhorn and dish. It features four output ports that can connect to four independent satellite receivers or two dual-tuner PVRs simultaneously. All receivers can watch programs on different polarizations without interfering with each other.
Q: Do I need an external switch when using a Quad LNBF?
A: No. This is one of the key advantages of a Quad LNBF. Traditional solutions require external DiSEqC switches and splitters to distribute signals, but a Quad LNBF provides four direct independent outputs – plug and play, no additional equipment needed.
Q: What does the 0.5dB noise figure mean?
A: 0.5dB is an industry-leading noise figure level. Lower noise figure means the LNB generates less self-noise. This means you get clear, pixelation-free pictures even in weak signal environments – such as remote areas, light rain fade, or when using smaller dish antennas.
Q: Does this LNB support full Ku-band?
A: Yes. Input frequency covers the complete 10.7~12.75GHz Ku-band. Automatic switching via 22KHz control signal: no 22KHz = low-band (9.75GHz LO), 22KHz present = high-band (10.6GHz LO).
Q: Can four receivers watch programs on different polarizations simultaneously?
A: Yes. The Quad LNBF has built-in vertical/horizontal polarization channels with ≥20dB port-to-port isolation. All four receivers can independently select polarization as needed – different programs, different polarizations, no interference.
Q: Is this LNB suitable for PVR (recording) applications?
A: Very suitable. You can connect two dual-tuner PVRs to record up to four different channels simultaneously. Alternatively, connect one dual-tuner PVR and two standard receivers for flexible watch + record combinations.
Q: How effective is the O-ring sealed waterproof design?
A: The O-ring seal effectively prevents rain and moisture from entering the LNB housing, protecting the circuitry from moisture damage. This is a critical reliability feature for outdoor installations – especially in rainy regions or unattended outdoor sites.
Q: What is the operating temperature range?
A: -30℃ to +60℃. This covers most climate conditions – from cold winters to hot summers.
