## Summary description

Active indoor/outdoor DVB‑T antenna BLOW 21-050 (model 21-050) provides reception of digital terrestrial television signals. The antenna is designed for use both inside and outside and includes an LTE filter to reduce mobile interference. Suitable for receiving DVB‑T broadcasts in home or small commercial installations where improved signal sensitivity and interference suppression are required.

## Long description

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.
