Outdoor active DVB-T/T2 antenna Evolveo HDO, powered amplifier for terrestrial digital TV reception

Evolveo HDO is an outdoor active DVB-T/T2 antenna with an integrated powered amplifier for reliable terrestrial digital TV reception. Designed for rooftop or wall mounting, the antenna improves signal strength and stability in areas with weak reception and supports DVB-T and DVB-T2 broadcasts, enabling clearer picture and sound for free-to-air channels. The antenna covers a wide frequency band and includes an LTE filter to suppress mobile operator interference, while an aerodynamic housing reduces snow accumulation and wind load.

Advantages

The integrated powered amplifier delivers high gain while maintaining low noise levels, improving reception for distant and marginal transmitters. A built-in LTE filter reduces interference from cellular networks. The antenna’s broadband coverage supports both UHF and VHF reception within the stated frequency ranges. A rotatable clamp and swivel joint make alignment simple without repeatedly loosening fasteners. Compact dimensions and a weather-resistant aerodynamic design enhance durability on rooftops and walls.

Suitable for

• Residential rooftop installations in areas with weak digital terrestrial reception
• Wall-mounted antenna points to improve free-to-air DVB-T/T2 channel quality
• Locations affected by mobile network interference where an LTE filter is needed
• Users who require 4K/UHD-capable reception from terrestrial broadcasts

How to use

Mount the antenna on a rooftop mast or wall bracket using the supplied clamp and fasteners. Connect the antenna coaxial cable to the TV tuner or external receiver via the F-type connector, and connect the supplied power adapter to supply DC 12 V to the antenna amplifier. Rotate the antenna using the swivel joint to find the best signal direction while checking signal strength on the TV or receiver; once optimal orientation is found, secure the mount. Ensure all outdoor cable connections are weatherproofed and the power supply is placed in a dry, ventilated location.

Usage recommendations

For best results, install the antenna as high as practical and with a clear line of sight to the broadcast transmitter. Use quality, well-shielded coaxial cable and waterproof connectors for outdoor runs. If reception remains poor, perform a channel scan after alignment and consider a mast-mounted rotator or professional alignment in difficult terrain. Regularly inspect the mounting and cable connections after severe weather to maintain stable reception.
