10 Best Cable TV Signal Boosters 2025 in the United States

The Reliable Cable Products 9 Port Bi-Directional Cable TV Splitter Signal Booster/Amplifier is designed to enhance your cable TV experience by providing eight amplified output ports. It ensures zero signal loss, both forward and reverse, making it great for maintaining a strong and consistent signal. However, it's not suitable for use with OTA antennas or satellite systems, so make sure your setup doesn't require those functionalities.

A standout feature is the modem port, which allows VoIP equipment to stay connected even during a power outage, crucial for maintaining phone services. The device is compatible with all standard and digital Cable TV services, including Triple Play phone service, but it might not work with cable systems that need MoCA technology. Check with your cable provider if MoCA is required for your system.

The installation is made easier with CamPort auto seizing F-ports and a design that allows for clean wiring. The durable powder-coated aluminum housing provides excellent protection against corrosion, while built-in surge protection and short-circuit protection add an extra layer of safety. The device comes with a 2-year warranty on the amplifier and a 1-year warranty on the power supply, offering some peace of mind. However, note that it does not include connection cables, so you will need to purchase those separately. This booster is ideal for those needing enhanced cable TV signal for multiple outputs but not for those relying on OTA antennas or satellite systems.

The Lindsay LSA84 is a 4-port cable TV and antenna signal amplifier designed to distribute a strong signal to multiple TVs or cable boxes without quality loss. It supports both standard and digital cable TV, as well as over-the-air (OTA) antenna reception, making it a good fit if you want to share a signal across several devices in your home. The built-in surge protection and weather-tight design add durability, which is helpful for different environments.

This amplifier is not meant to improve weak signals or work with satellite systems, existing amplifiers, or MoCA networks. It simply boosts an already good signal, so if your signal is poor to start with, it may not help. With four outputs, it provides flexibility for multiple connections, but users should note it’s not compatible with systems that already have an amplifier. The included power supply and terminators make setup straightforward.

For those with a decent cable or antenna signal who want to share it cleanly across several TVs without pixelation or signal loss, this booster offers a reliable, safe, and straightforward solution. However, it’s not suitable as a fix for weak signals or satellite setups, so those users will need a different product.

The ANTRONIX MRA Series Cable TV RF Broadband Amplifier offers a solid 15dB gain, ideal for boosting your cable TV signal strength. The frequency range of 5-1002 MHz is quite broad, allowing it to support a wide array of channels and services. However, it comes with only one output, which might be a limitation if you need to connect multiple devices.

The noise figure isn't specified, but the patented auto-seizing F-port and surge protection features suggest reliability and low maintenance. Compatibility-wise, it supports the true 5-42 MHz return band and a full 1 GHz downstream spectrum, offering more useable bandwidth for various applications. Installation is made easier by the micro-housing design, allowing for simplified coaxial cable management in tight spaces.

Additionally, the self-resetting circuit protection against short-circuits is a nice touch for ensuring durability and reducing maintenance costs. This amplifier is best suited for individuals looking for a reliable, easy-to-install solution to boost their cable TV signal, particularly if they don't require multiple outputs.
