Omnidirectional Antenna DeLOCK 12438

The DeLOCK 12438 is an omni-directional antenna designed for indoor and outdoor use that covers the TETRA BOS frequency range of 380–410 MHz. It has a compact height of 522 mm and a black finish. The antenna matches a 50 Ω system and supports a power handling capacity of up to 50 W, making it suitable for various communication setups requiring the 0.38–0.41 GHz band.

Advantages

The antenna provides an omni-directional radiation pattern with a maximum gain of 2.5 dBi, enabling uniform coverage around the installation point. Its design allows operation both inside buildings and in outdoor environments, and the 50 Ω impedance ensures compatibility with most radio equipment. The product is lightweight and delivered in a simple polybag package.

Suitable for

• TETRA BOS voice and data communications in the 380–410 MHz band
• Indoor base station augmentation and small outdoor deployments
• Applications requiring a compact, low-gain omni-directional antenna

How to use

Mount the antenna in a location that provides the best line-of-sight for the coverage area required, taking into account building structures and nearby obstacles. Connect the antenna to compatible radio equipment using a 50 Ω feedline and appropriate connectors. Verify that the connected equipment operates within the 380–410 MHz band and does not exceed the antenna's 50 W power rating. For outdoor installations, ensure the mounting hardware and feedline are weatherproofed as needed.

Recommendations

For optimal performance, place the antenna at an elevated position clear of large metallic objects and sources of interference. Use quality 50 Ω coaxial cable and proper connectors to minimise signal loss and ensure secure, weather-resistant connections for outdoor use.
