• Optional multi‑function support – Some variants include integrated support for additional antennas or signal splitters.

Design and Build Quality

The H22D’s flat plate design is engineered to reduce aerodynamic drag, which translates into lower wind resistance and less vibration during storms. The dish’s surface is coated with a high‑quality, UV‑resistant paint that maintains its appearance for years. The internal structure is reinforced with a lightweight yet sturdy frame, ensuring the dish remains stable under all weather conditions.

Material Composition

The dish is made from high‑density polyethylene (HDPE) combined with a lightweight aluminum frame. This combination offers excellent thermal stability, preventing warping or distortion when temperatures fluctuate.

Dimensions and Weight

The H22D measures 220 mm in diameter and weighs approximately 1.2 kg, making it easy to transport and install without the need for heavy equipment.

Interchangeable Single LNB System

The interchangeable LNB is a standout feature that allows users to adapt the dish to different receivers or upgrade their system without replacing the entire antenna. The LNB module can be swapped in a matter of minutes, thanks to a simple mounting interface.

Compatibility

The LNB is compatible with a wide range of satellite receivers, including those that support DVB‑S, DVB‑S2, and UHD 4K. It also works seamlessly with receivers that require DAB/DAB+ or traditional radio frequencies.

Installation Process

1. Mount the dish on a suitable bracket or roof panel.
2. Attach the LNB to the dish’s mounting point using the provided screws.
3. Connect the coaxial cable from the LNB to your receiver.
4. Tune the receiver for optimal signal strength.

Performance Characteristics

The H22D delivers exceptional signal quality, thanks to its high gain and precise alignment capabilities. Users report reliable reception of 4K UHD channels, even in areas with moderate interference.

Signal Gain

The dish’s 34.5 dBi gain ensures that weak satellite signals are amplified sufficiently for clear reception. This high gain is particularly beneficial in urban environments where signal obstructions are common.

Bandwidth and Frequency Range

The dish supports a broad frequency range, covering:

• 2.3–3.8 GHz for DVB‑S
• 3.8–4.2 GHz for DVB‑S2
• 4.0–5.0 GHz for UHD 4K
• 0.5–1.7 GHz for DAB/DAB+
• 0.3–1.7 GHz for UKW/MW/LW

Installation and Setup Guide

Installing the H22D is straightforward, even for beginners. Follow these steps to achieve optimal performance:

Step 1: Site Survey

Identify a clear line of sight to the satellite. Avoid obstructions such as trees, buildings, or large metal objects.

Step 2: Mounting

Select a sturdy mounting bracket or roof panel. Secure the dish using the provided screws and ensure it is level.

Step 3: LNB Attachment

Attach the interchangeable LNB to the dish’s mounting point. Tighten all screws securely.

Step 4: Cable Routing

Run a high‑quality coaxial cable from the LNB to your receiver. Use weatherproof connectors and seal any gaps with silicone.

Step 5: Receiver Configuration

Power on your receiver and navigate to the satellite settings. Input the correct frequency parameters for your region.

Step 6: Fine‑Tuning

Use the receiver’s signal strength meter to adjust the dish orientation until you achieve maximum gain.

Maintenance Tips

To keep the H22D in top condition, perform regular checks:

• Inspect the dish surface for scratches or paint damage.
• Check mounting screws periodically to ensure they remain tight.
• Clean the LNB connector with a dry microfiber cloth to prevent signal loss.
• Verify cable integrity by inspecting for kinks or cuts.
