Antenna DELOCK 12085 active omnidirectional DAB+ DVB‑T2 gain 5–25 dB

The DELOCK 12085 active omnidirectional antenna is designed for DAB+ digital radio and DVB‑T2 terrestrial television reception. With an adjustable gain range from 5 to 25 dB, the antenna helps to improve reception in areas with weak or variable signal strength. Its omnidirectional design receives signals from all horizontal directions, making it suitable for stationary home installations and mobile setups where consistent coverage is required without manual repositioning.

Advantages

The antenna provides a configurable amplification range to adapt to different signal environments, reducing signal dropouts and improving audio and video quality. Its omnidirectional pattern eliminates the need for directional aiming, simplifying installation. The active element increases sensitivity for distant transmitters while maintaining compact physical dimensions suitable for indoor or small outdoor mounting.

Suitable for

• Improving DAB+ digital radio reception in urban fringe or rural areas
• Enhancing DVB‑T2 terrestrial TV signal quality for homes and caravans
• Mobile installations where fixed orientation is impractical
• Setups requiring adjustable gain to match local signal conditions

Key specifications

• Supported standards: DAB+ and DVB‑T2
• Gain: adjustable from 5 dB to 25 dB
• Radiation pattern: omnidirectional (horizontal plane)
• Powering: active antenna requires power supply for the amplifier
• Typical mounting: indoor or small outdoor mast/bracket mounting
• Connector type: standard coaxial connection compatible with common receiver inputs

How to use

Mount the antenna in a location with minimal obstructions and as high as practical to reduce terrain and building interference. Connect the antenna to the receiver or amplifier input using a suitable coaxial cable and ensure the antenna’s power supply is connected if required. Adjust the gain control to a lower setting first and increase gradually while monitoring signal strength and quality on the receiver to avoid overload or noise amplification. Secure all connections and verify reception across desired DAB+ radio stations and DVB‑T2 TV channels.

Recommendations

For best results, place the antenna away from large metal objects and active electronic devices that can cause interference. In mobile or caravan installations, check signal quality after each relocation and adjust the gain as needed. If reception remains poor, try elevating the antenna or using a higher-quality, low-loss coaxial cable.
