Broadband Antenna Amplifier Alcad CA-215

Alcad CA-215 is a broadband antenna amplifier engineered to improve reception of terrestrial TV and radio signals. The unit delivers wideband amplification across the VHF and UHF frequency ranges to reduce signal loss between an outdoor antenna and indoor receivers. Designed for residential installations and small communal systems, the amplifier helps maintain stable picture and sound quality where signal strength is variable or attenuated by long cable runs.

Advantages

The amplifier provides consistent gain across a broad frequency range, minimizing channel-to-channel variation and preserving signal integrity. Its compact housing facilitates easy mounting near the antenna or mast, and the low-noise amplification improves weak-signal performance without introducing significant distortion. The Alcad CA-215 supports both television and FM radio signals, offering a single solution for multi-service reception enhancement.

Suitable for

• Residential rooftop or attic TV and FM radio reception
• Small communal or multi-dwelling antenna systems
• Locations with long coaxial cable runs where signal loss occurs
• Areas with moderate to weak terrestrial broadcast signals

Key specifications

• Broadband amplification covering standard terrestrial VHF and UHF bands
• Low noise figure to improve weak-signal reception
• Compact, weather-resistant housing suitable for mast mounting
• Power supply via coaxial feed or separate power injector (depending on installation)
• F-type or IEC-compatible coaxial connectors for antenna and output connections

How to use

Install the amplifier as close to the antenna as practical to minimize unamplified cable length. Connect the antenna feed to the amplifier input and run the amplified output to the distribution cable or directly to the receiver. Provide power according to the installation method: either inject power through the coaxial line from an indoor power supply or use the designated external power injector if required. After installation, tune the receiver and check signal levels and picture quality; adjust cable routing and grounding as needed to optimize performance.

Usage recommendations

Place the amplifier at the antenna mast or in an outdoor-rated enclosure to reduce signal loss. Avoid over-amplification in areas with very strong signals by verifying signal levels after installation; in such cases, an attenuator may be required. Ensure proper grounding and weatherproofing of connectors to maintain long-term reliability.
