HOW TO PERFORM AN AUTOMATIC CHANNEL SEARCH ON ASTRA 19.2°E
Scanning for channels on Astra 19.2°E is the fastest way to access hundreds of Free-to-Air (FTA) European channels, including major German, French, and international news networks. As a technical support engineer, I will guide you through the two most effective methods: Network Search (NIT) and Blind Scan.
Step-by-Step Astra 19.2°E Installation Guide
1. Hardware Readiness Check
Before initiating the software scan, verify your physical connections:
- LNB Connection: Ensure your coaxial cable is securely tightened to the LNB IN port on your TV or satellite receiver.
- Dish Alignment: Your dish must be precisely pointed at 19.2° East. In most of Europe, a 60cm to 80cm dish is ideal for high-signal stability.
- Cable Integrity: Use a high-quality RG6 copper cable to prevent signal loss during high-frequency scans.
2. Satellite and LNB Configuration
Open your device’s Menu using the remote and navigate to Installation or Antenna Settings:
- Satellite Selection: Select Astra 19.2E from the pre-installed satellite list.
- LNB Type: Ensure this is set to Universal (9750/10600). If this parameter is wrong, the receiver will fail to lock onto any frequencies.
- DiSEqC Settings: If you use a multi-feed system (e.g., receiving both Hotbird and Astra), assign the correct DiSEqC port (usually LNB 1 or LNB 2) to Astra.
3. Automatic Search Methods
Depending on your receiver model, choose one of the following:
- A) Network Search (NIT) – Recommended: This is the most efficient method as it uses a “Home Transponder” to download the latest frequency map directly from the satellite.
- Go to the Manual Scan or Transponder menu.
- Enter a strong reference frequency: 10714 H 22000 or 12604 H 22000.
- Crucial Step: Set the “Network Search” (or NIT) option to “ON”.
- Start the search. The device will automatically find all other active transponders.
- B) Blind Scan: If your receiver supports this, it will scan the entire frequency spectrum without needing any manual input.
- Select “Blind Scan” as the scan mode.
- Enable the “FTA Only” filter to avoid cluttering your list with encrypted channels you cannot watch.
4. Post-Installation Optimization
Once the scan is complete, check your channel list for clarity. If you experience “No Signal” messages on specific channels:
- LNB Skew: Slightly rotate the LNB in its holder (clockwise or counter-clockwise) to maximize the Signal Quality percentage. Aim for at least 70%.
- Weather Margin: Ensure your signal is strong enough to withstand rain (Rain Fade).
