To boost your satellite internet signal, realign your dish for optimal reception, remove any physical obstructions like trees, upgrade your modem and cables, and use a signal booster to enhance the signal strength. Adjust Satellite Dish Alignment Aligning your satellite dish correctly is one of the cheapest and most effective methods of satellite internet signal […]

The 70cm satellite band refers to the 430-440MHz UHF frequency, which is commonly used for amateur satellite communications (such as the ISS downlink frequency 437.800MHz). Operation requires an amateur radio license, an omnidirectional antenna and a receiver tuned to this band, and compensation for Doppler shift (±10kHz). What is 70cm Band? Last year when AsiaSat

The optimal FTTH splitter ratios—1:2, 1:4, 1:8—vary based on user density and service needs, balancing signal quality and cost efficiency for targeted subscriber reach. 1:2, 1:4, 1:8 Splitters 1:2 Splitters – Luxury Other URLs For luxury condos or small residential buildings with a small number of customers, a 1:2 splitter can be the most effective

Dolph Microwave is one of the leading names in coaxial cable connectors industry. Dolph Microwave is perhaps best known for precision-engineered solutions based on customer-supplied mechanical and RF specifications. However, the one component of their business that functions as a signature is in between waveguide to coaxial adapters – which have become known as such

In FTTH, S1 links the central office to aggregation nodes using single-mode fiber for long distances up to 20 km. S2 connects these nodes to subscriber homes, often spanning 2-5 km. Purpose and Placement S1 and S2 are essential elements in the structure of the Fiber to the Home network, and each has a specific

Active couplers require power to amplify signals, ideal for long distances, whereas passive couplers, power-free, split signals without amplification, suitable for short ranges. External Power Required Active couplers require an external power source to work effectively and so are quite different from their passive counterparts. This is due to the fact that, inside the box,

The directivity of a directional coupler, typically measured in decibels (dB), ranges from 20 dB to 40 dB, indicating its ability to differentiate between forward and reverse waves. Definition Directivity is a parameter describing how well a coupler is capable of distinguishing how much power is transferred in the forward direction and how much is

7 elements of antenna tuning: 1. Azimuth angle accurate to ±1° (calibrated with a compass); 2. Pitch angle adjusted according to frequency band (20-50° for satellite communication); 3. Polarization direction matching signal source (vertical/horizontal); 4. Real-time monitoring of signal strength (＞-70dBm); 5. Avoid obstacles (＞3 meters spacing); 6. Connector torque 0.9N·m; 7. Install a low-noise

Component Selection Choosing Multi-Band Feed Systems Integrating multiple frequency bands into the antenna feed network requires the introduction of a multi-band feeding system, so the choice is to combine different frequency bands. To determine the appropriate feed system, a list of frequency bands owned by the network needs to be compiled, which can be, for

Directional couplers typically create a 90-degree phase difference between outputs, crucial for precise signal processing in applications like 5G networks operating at 28 GHz. Fundamental Design Directional couplers are critical elements in the RF and microwave engineering, which are designed to split the input signal with a defined phase difference, primarily 90 degrees. Such configuration
