Gain
Installing this amplifier close to the antenna can significantly enhance reception, boosting the number of available channels from 25 to over 40.

The Reliable Cable Products 9 Port Bi-Directional Cable TV Splitter Signal Booster/Amplifier is designed to improve cable TV signal distribution with its eight amplified output ports. One of its key strengths is that all ports are lossless, ensuring no signal degradation in both forward and reverse directions, which is ideal for maintaining high-quality signal strength across multiple devices. Additionally, it features an active return which is beneficial for users with cable TV services that require signal return capabilities. The modem port is especially useful for VoIP equipment, ensuring uninterrupted service during power failures, which can be a critical feature for those relying on digital phone services.

The amplifier is compatible with standard and digital cable TV services, including the popular Triple Play services that bundle TV, internet, and phone. However, it is not recommended for use with OTA antennas and is incompatible with satellite systems, which limits its versatility for some users. Furthermore, the product is not MoCA capable, which might be a drawback for users whose cable systems require MoCA support.

The product construction includes a durable powder-coated aluminum housing for corrosion resistance and features surge protection to safeguard against electrical issues. It also comes with a 2-year warranty for the amplifier and a 1-year warranty for the power supply, offering some peace of mind. However, it does not include connection cables, which users will need to purchase separately. This amplifier is well-suited for users looking to enhance their cable TV signal distribution across multiple devices while maintaining signal quality and reliability.

Noise Figure
Frequency Range

Most important from
690 reviews

Gain
Boosts digital over-the-air signal strength to multiple TVs, even when the antenna is only 10 feet high.
Noise Figure
Easy to mount and comes with a power supply and two terminating caps for unused outputs, keeping the amp stable and noise-free.
Frequency Range
The amplifier compensates for crippling signal losses caused by cheap passive splitters and long cable runs, ensuring rock-solid signal at both TVs on all VHF and UHF channels.
Power Supply
Easy to mount and comes with a power supply and two terminating caps for unused outputs, keeping the amp stable and noise-free.

The Reliable Cable 4-Port Digital Signal Amplifier is designed to enhance TV and internet signal quality by offering one input and four outputs, making it suitable for households with multiple TVs or cable boxes. One of its key strengths is its integrated equalizer, which adjusts amplification based on frequency, ensuring high frequency signals are boosted more, especially over long cable runs.

This feature is crucial for maintaining signal integrity in larger setups. The amplifier provides a modest gain of 0dB at lower frequencies (54MHz) and up to 7.5dB at higher frequencies (1000MHz), making it effective for both cable TV and OTA antenna systems. Users should note that it is not compatible with systems already equipped with an amplifier or pre-amplifier, nor is it suitable for satellite systems.

Safety features such as short-circuit protection and surge resistance enhance its reliability, while the weather-tight seal ensures it can operate in diverse environmental conditions. However, some potential drawbacks include its relatively low gain at lower frequencies, which might not be sufficient for areas with very weak signals. Additionally, the device’s small size (3.75 x 4.56 x 1.06 inches) and lightweight (1.1 pounds) could be seen as less robust compared to bulkier, more industrial-grade options. This signal amplifier is ideal for users looking to distribute a clear TV signal across multiple devices in a medium to large household, ensuring stable and enhanced signal quality.

Buying Guide for the Best Tv Signal Amplifiers

When choosing a TV signal amplifier, it's important to understand that this device is designed to boost the strength of the TV signal received by your antenna. This can be particularly useful if you live in an area with weak signal reception or if you have multiple TVs connected to a single antenna. The right amplifier can improve picture quality and reduce signal dropouts. To make an informed decision, you should consider several key specifications that will help you determine which amplifier is best suited for your needs.
GainGain is a measure of how much the amplifier can increase the strength of the signal. It is usually measured in decibels (dB). Higher gain means a stronger signal boost. If you live far from the broadcast towers or have many obstacles like buildings or trees, you might need an amplifier with higher gain (20-30 dB). For areas with moderate signal strength, a lower gain (10-20 dB) might be sufficient. Choose the gain based on your distance from the signal source and the number of obstructions in your area.
Noise FigureThe noise figure indicates how much noise the amplifier adds to the signal. It is measured in decibels (dB), and a lower noise figure means less added noise, resulting in a clearer signal. A noise figure below 3 dB is considered good. If you are in an area with weak signals, a lower noise figure is crucial to maintain signal quality. For stronger signal areas, this spec is less critical but still important for optimal performance.
Frequency RangeThe frequency range specifies the range of signal frequencies the amplifier can handle. TV signals are broadcast over a range of frequencies, typically from VHF (Very High Frequency) to UHF (Ultra High Frequency). Ensure the amplifier covers the full range of frequencies used in your area. For most users, an amplifier that supports both VHF and UHF frequencies is ideal, as it will cover all possible channels.
Number of OutputsThe number of outputs indicates how many devices you can connect to the amplifier. If you have multiple TVs or other devices that need a signal boost, look for an amplifier with multiple outputs. Single-output amplifiers are suitable for one TV, while multi-output amplifiers (2-4 outputs) are better for households with several TVs. Choose based on the number of devices you need to connect.
Power SupplyTV signal amplifiers can be powered in different ways, such as through a direct power outlet or via a USB connection. Consider where you will place the amplifier and the availability of power sources. If you plan to install it near your TV, a USB-powered amplifier might be convenient. For attic or outdoor installations, a direct power outlet might be more reliable. Choose the power supply option that best fits your installation setup.
AdjustabilitySome amplifiers offer adjustable gain control, allowing you to fine-tune the signal strength. This can be useful if you experience signal overload or if the signal strength varies. Adjustable gain is beneficial for users who want more control over their signal quality. If you prefer a set-and-forget solution, a fixed-gain amplifier might be more suitable. Consider your need for flexibility and control when choosing this feature.
