In 2025, waveguide manufacturing will use nanoimprint lithography (±10nm accuracy), low-loss silicon nitride (≤0.1dB/cm), combined with PECVD deposition (300°C) and femtosecond laser cutting (roughness <50nm), with AOI inspection yield >99.8%. How to Select Materials Last month we just handled the vacuum leak incident of the APT-6D satellite’s waveguide components – the flange material’s on-orbit thermal […]

The cost of VSAT antennas in 2025 will be affected by five factors: 1) Antenna size, which is usually 1.2 meters to 3 meters, and the price increases with size; 2) Data transmission rate, with differences in cost per Mbps; 3) Installation difficulty and labor; 4) Equipment brand and quality; 5) Post-operation and maintenance support.

Satellite and cellular antennas perform differently in remote areas: 1) Satellites have wide coverage, reaching 99% of the world; 2) Cellular relies on base stations, with coverage as low as 30%; 3) Satellite latency is about 600ms, while cellular latency is about 50ms; 4) Satellite equipment is expensive, requiring large initial investments; 5) Cellular data

There are seven major components of satellite antennas that affect signal quality: 1) reflector (gain up to 25-35dB); 2) feed source (matching impedance 30-70Ω); 3) LNB noise factor <1dB; 4) power amplifier output 1-10W; 5) polarization angle error needs to be <1°; 6) bracket stability; 7) external shielding. Regular inspections can ensure optimal performance. LNB

Satellite WiFi antenna maintenance: 1) Check once a quarter and remove any snow or dust; 2) Use a soft-bristled brush to gently sweep the surface; 3) Avoid using corrosive cleaning agents; 4) Ensure that the antenna reflective surface is not blocked; 5) Apply a UV protective layer regularly (annually). These steps will help prevent signal

The difference between VSAT and Satcom antennas: 1) VSAT operates in the Ku or Ka band and has a high signal strength; 2) Satcom often covers the C band and has a wide range; 3) VSAT diameter is usually 0.6-2.4 meters, which is conducive to rapid deployment; 4) Satcom antennas are larger and can provide

There are three frequency bands to consider when selecting a satellite antenna LNB: C-band (3.7-4.2 GHz), Ku-band (10.7-12.75 GHz), and Ka-band (18.3-31 GHz). Choose the appropriate LNB based on the frequency range of the signal you need to receive to ensure clear reception. For example, Ku-band is often used to receive high-definition programs. Application Scenarios

Three steps to install a satellite antenna: 1. Choose an open location and make sure there are no obstructions in front of the antenna. The ideal viewing angle should be greater than 90 degrees. 2. Use a compass and incline meter to accurately locate the azimuth and elevation. 3. Firmly fix the antenna base to

When choosing a VSAT antenna, consider: 1. Diameter, usually between 0.9 and 2.4 meters; 2. Gain level, high gain improves signal quality; 3. Frequency band support, such as Ku or Ka band; 4. Ease of installation; 5. Durability, ensuring it can withstand severe weather. The right choice can achieve a stable connection reliability of more

To align the satellite antenna, you need to use: 1. A satellite signal strength meter to ensure that the error is within 3 degrees; 2. A compass to determine the azimuth; 3. An incline meter to adjust the elevation; 4. A wrench to fix the antenna. Correct settings can increase the signal strength to more
