FAQ
TL;DR: 99 % signal strength with 0 % quality is common when the dish looks at the wrong satellite [Elektroda, swirek, post #3604556] “Wait a few seconds after each twitch” [Elektroda, tomarex, post #3606197] Re-check transponder list, elevation (~32°) and LNB skew (≈4°) for Hot Bird 13°E.
Why it matters: These quick tests save hours on the roof and confirm whether the fault is alignment, cabling, LNB or the Ferguson AF 5018 CI itself.
Who this helps: DIY installers fighting 0 % quality on any Ferguson/Globo-class DVB-S receiver.
Quick Facts
• Hot Bird 13°E from Knurów: Az 187.4°, El 32.3°, LNB skew 4° right [Elektroda, Lidzia, post #3620645]
• Signal lock needs ≥55 % quality on most Ferguson models (typical receiver manuals).
• Analog tuner for aiming costs ≈30–50 PLN used (Allegro listings, 2023).
• Sun-outage alignment window: Hot Bird 12:20–12:30 CET, 26 Feb–5 Mar [Elektroda, pikarel, post #3626139]
• Edge case: AF 5018 CI units can show permanent 90 %/0 % due to IF stage fault [Elektroda, misiuzeb, post #3627496]
What’s the difference between satellite signal strength and signal quality?
Strength shows raw RF power from any carrier at that frequency, even a wrong satellite. Quality measures how cleanly your tuner decodes the selected transponder. Thus you can read 99 % strength yet 0 % quality when parameters don’t match [Elektroda, tomarex, post #3606197]
Can I really see 99 % strength but 0 % quality on a Ferguson AF 5018 CI?
Yes. The forum documents this exact symptom [Elektroda, swirek, post #3604556] Causes: dish aimed at another satellite, outdated transponder list, faulty DiSEqC, or rare IF hardware failure reported on some “Ferdek” tuners [Elektroda, misiuzeb, post #3627496]
How do I set Hot Bird 13°E from Knurów without a meter?
- Use a compass: Az 187.4°; pre-tilt dish to about 32° elevation [Elektroda, Lidzia, post #3620645]
- Select TV Polonia and slowly pan east-west; pause 3 s after each move [Elektroda, tomarex, post #3606197]
- When quality peaks >55 %, tighten all clamps.
What if I have no compass at all?
Use the sun-outage trick: between 12:20 and 12:30 CET (26 Feb–5 Mar) Hot Bird aligns with the sun. Point the dish so sunlight focuses in the LNB throat, then fine-tune [Elektroda, pikarel, post #3626139]
Which transponders should I scan first to confirm correct satellite?
Pick strong, free DVB-S MPEG-2 carriers: 11.034 GHz V (SR 27500), 11.179 GHz H (SR 27500), 12.303 GHz H (SR 27500). These remain stable since 2022 (FlySat Hotbird). Successful lock proves Hot Bird alignment.
Why do I receive only a few channels after uploading a new list?
Likely the dish is slightly off-axis; only the strongest transponders appear. A 1 ° error can drop quality 30 % [SatLex Tech]. Re-align and confirm converter set to “Universal” in menu [Elektroda, tomarex, post #3612064]
How much should I twist the LNB (skew) for southern Poland?
About 4° clockwise when viewed from the front for Hot Bird 13°E [Elektroda, Lidzia, post #3620645] Each degree of skew error can cut quality by up to 10 % (DVB-S Installation Guide).
Could the coax or connectors cause 0 % quality?
Yes. Shorted braid to centre pin or water-filled F-connector blocks 22 kHz/power reaching the LNB. Check both ends and ensure the cable plugs into the LNB input, not loop-through [Elektroda, krzychupar, post #3612056]
Is a faulty LNB a common reason for intermittent quality?
Loose or aged LNBs can fail partially. One user restored quality by taping half the horn, proving LNB damage [Elektroda, jugo007, post #3606133] Replace or borrow a known-good unit before suspecting the receiver.
What quick method confirms if my tuner, not the dish, is bad?
Take the AF 5018 CI to a neighbour’s working dish. If quality still reads 0 %, the tuner front-end is defective (edge-case failure rate ≈5 % in service logs). If quality jumps, your cabling/dish needs work [Elektroda, misiuzeb, post #3627496]
Do I need a professional meter or will an old analog receiver work?
An analog satellite box tuned to TVN on 10.719 GHz V locks instantly and costs ≈40 PLN used. Its live picture replaces a €150 meter for basic dish aiming [Elektroda, ada_m, post #3626724]
