Boost your cable TV signal with the Tuoying YB-8020 20dB CATV RF Signal Amplifier — a CE-certified indoor amplifier covering the full 45–860MHz frequency range. Featuring a 1-input / 2-output split design and an adjustable 0–10dB attenuator (ATT) knob, this amplifier gives you precise control over your output level, ensuring crystal-clear reception across multiple TV sets without overloading your signal chain.

Key Features

20dB Gain — dramatically strengthens weak RF/cable TV signals across the 45–860MHz band
1-In / 2-Out Design — split one incoming cable signal to feed two TVs or devices simultaneously
Adjustable ATT Knob (0–10dB) — fine-tune input attenuation to prevent signal overload and maintain optimal output (80–105dBV)
Wide Input Level Range — accepts input signals from 57dBV to 80dBV (standard 72dBV)
75-Ohm Impedance — compatible with standard CATV coaxial cable infrastructure
±1.5dB Amplitude Frequency Response — flat, consistent performance across the entire frequency range
CE Certified — meets European conformity safety and performance standards
Indoor Use — compact design ideal for home and light commercial installations
220V / 50Hz Power Supply — stable operation on standard mains power
Maximum Cable Run ~200M — supports long-distance distribution to terminals (frequency and user count dependent)

Usage Tips

Check your input level first — the amplifier requires an input signal between 57–80dBV. Signals that are too weak before amplification cannot be fully recovered by the amplifier alone.
Use the ATT knob carefully — if you see mesh or wiper-pattern interference on screen, rotate the ATT knob counter-clockwise to reduce input level until the image clears. This prevents amplifier overload.
Multi-TV households — for three or more TVs, use this amplifier in combination with a signal splitter or distributor for best results.
Weather precautions — during heavy lightning, disconnect power to protect the unit. This amplifier is designed for indoor use only; keep it away from moisture and excessive heat.
Terminal level target — aim for 60–75dBV at each TV terminal for optimal picture quality.

Frequently Asked Questions

Q: What is the difference between the YB-8020 and YB-8028 CATV amplifier models?

A: The YB-8020 provides 20dB of gain and supports cable runs of approximately 200 metres, while the YB-8028 offers 28dB of gain with a maximum cable run of around 250 metres. Both models share the same 45–860MHz frequency range and adjustable 0–10dB ATT control. Choose the YB-8020 for standard home use and the YB-8028 for longer cable runs or larger distribution setups.

Q: Can I use this CATV RF signal amplifier with more than two TVs?

A: The YB-8020 features a 1-in / 2-out design, providing two output ports. For three or more TVs, it is recommended to pair this amplifier with a compatible signal splitter or distributor. Using the amplifier's output ports in combination with a quality splitter helps maintain signal integrity to each terminal, keeping levels within the optimal 60–75dBV range at each TV.

Q: What should I do if my TV picture shows mesh or wiper-pattern interference after installing the amplifier?

A: Mesh or wiper-pattern interference typically indicates the amplifier is receiving an overloaded input signal. Turn the ATT (attenuator) knob counter-clockwise gradually until the interference disappears and the image stabilises. If the interference was already present before the amplifier, it may be caused by external sources such as local broadcast stations or wireless devices — in this case, consider using the branch output port or a higher-attenuation splitter.

Q: Is the Tuoying YB-8020 suitable for outdoor installation?

A: No — this unit is designed exclusively for indoor use. It should be kept away from moisture, rain, and direct heat sources. During severe thunderstorms, it is recommended to disconnect the amplifier from the power supply to avoid potential damage from lightning strikes.

Q: What cable and connector types are compatible with this amplifier?

A: The YB-8020 uses a standard 75-ohm impedance, which is compatible with the coaxial cable (such as RG6 or RG59) commonly used in CATV installations. Ensure all connection ports, branch distributors, and terminal boxes are in good condition, as poor-quality cables or connectors can significantly reduce signal quality regardless of amplifier performance.
