Indoor/Outdoor Active DVB‑T Antenna BLOW 21‑050 with LTE filter, model 21-050

The BLOW Indoor/Outdoor Active DVB‑T Antenna 21-050 is a compact amplified antenna designed to receive digital terrestrial television signals (DVB‑T). Built for both indoor and outdoor installation, it combines a low-profile form factor with active amplification to improve signal sensitivity in areas with weak or variable reception. An integrated LTE filter reduces interference from nearby mobile networks, helping to maintain clearer television reception in urban and suburban environments.

Advantages

This antenna offers improved DVB‑T signal gain through an internal amplifier, increasing the likelihood of stable picture and sound where passive antennas fail. The weather-resistant housing allows for outdoor mounting while remaining suitable for indoor placement when external installation is impractical. The included LTE filter attenuates unwanted mobile network frequencies, reducing pixelation and signal dropouts caused by nearby cellular transmitters.

Suitable for

• Residential reception of digital terrestrial television in apartments and houses
• Small commercial locations such as cafés, offices or waiting areas
• Places with weak DVB‑T signal where amplification is required
• Areas affected by mobile phone interference where LTE filtering is beneficial

Key specifications

• Compatibility: DVB‑T terrestrial digital TV
• Mounting: indoor and outdoor installation capable
• Amplifier: active amplification to increase signal sensitivity
• Interference suppression: built-in LTE filter for reducing mobile network noise
• Housing: weather-resistant design suitable for external use
• Connector type: standard RF coaxial output for TV tuners and set‑top boxes

How to use

Mount the antenna in a location with the best possible line of sight toward broadcast transmitters, such as on a rooftop, balcony, or near a window. Connect the antenna output to the TV or set‑top box coaxial input using appropriate coaxial cable and, if required, a compatible power inserter for the active amplifier. After connection, run an automatic channel scan on the television to detect available DVB‑T channels and adjust antenna position to optimize signal strength and quality.

Usage recommendations

Use high-quality coaxial cable and proper weatherproofing for outdoor connections to maintain signal integrity. If reception remains poor, try elevating the antenna or relocating it to reduce obstructions. In installations with long cable runs, consider placing the power supply close to the antenna to compensate for cable loss.
