Aerial/TV Antenna BLOW LNA 177-5G with 30 dB LNA gain (original)

TV antenna BLOW LNA 177-5G is a terrestrial aerial with an integrated low-noise amplifier that provides 30 dB gain. It is designed to improve reception of digital and analogue terrestrial television signals in areas with weak coverage or where cable losses reduce signal quality. The antenna is intended for residential or small-installation use and helps maintain a stable signal on longer cable runs.

Advantages

The integrated LNA with 30 dB gain raises incoming signal levels while keeping amplifier noise low, improving the signal-to-noise ratio for clearer picture and sound. Its design reduces the need for multiple distribution amplifiers in small systems and compensates for attenuation on long coaxial feeds. The antenna's compatibility with terrestrial digital and analogue broadcasts makes it versatile for different reception environments.

Suitable for

• Homes located in areas with weak terrestrial TV signal
• Small apartments or houses requiring enhanced antenna gain
• Installations with long coaxial cable runs where signal attenuation is a concern
• Systems receiving both digital and analogue terrestrial television

Key specifications

• Type: terrestrial TV antenna with built-in low-noise amplifier
• Amplifier gain: 30 dB
• Intended reception: digital and analogue terrestrial TV
• Use case: indoor/roof or external installation for domestic and small installations
• Function: signal amplification to compensate for weak reception and cable losses

How to use

Mount the antenna in a location with the best possible line of sight to broadcast towers, typically on a roof, mast, or high external wall. Connect the antenna output to the TV or to a distribution system using coaxial cable, and provide power to the LNA as required by your setup (via a power inserter or powered splitter if applicable). After installation, perform an auto-tune or channel scan on the television to detect available channels and adjust antenna orientation for the best signal strength and quality.

Usage recommendations

Place the antenna as high as practical and clear of large obstructions; minimize coaxial cable length and use quality, well-shielded cable to reduce losses. If multiple receivers are used, add an appropriate distribution amplifier after the LNA rather than splitting the signal before amplification. Ensure the amplifier power supply is compatible with the installation to prevent performance issues.
