Antenne omnidirectionnelle DeLOCK 12411

The DeLOCK 12411 omni-directional antenna is designed for digital radio (DAB+) reception and provides an integrated amplifier to enhance signal strength. It operates in the 0.174–0.24 GHz frequency range, offers a maximum gain of 23 dBi and presents a 50 Ω impedance with an SMB connector. Its compact dimensions and low power consumption make it suitable for various installation environments where improved DAB+ reception is required.

Advantages

The antenna’s integrated amplifier improves weak digital radio signals to achieve more stable reception. With a high gain of 23 dBi and a low VSWR of 2.0:1, the DeLOCK 12411 delivers efficient signal performance. The SMB connector and 50 Ω impedance ensure compatibility with standard radio equipment, while the small form factor simplifies installation in tight spaces.

Suitable for (tasks / use cases)

• Receiving DAB+ / digital radio broadcasts
• Improving reception in areas with weak radio signals
• Installation in vehicles, home audio systems, or compact radio devices

How to use

Connect the DeLOCK 12411 antenna to the receiver’s SMB antenna input ensuring the connector is correctly aligned. Place the antenna in a position with minimal obstructions and, if possible, elevated or near a window to improve line-of-sight to broadcast transmitters. Power is supplied via the receiver (19 mA consumption); verify the receiver supports external powered antennas if required.

Recommendations

For best DAB+ reception, mount the antenna away from large metal objects and other RF sources. If reception remains weak, try repositioning the antenna or using an external antenna cable with proper shielding and 50 Ω impedance to reduce losses.
