Omnidirectional antenna DeLOCK 12455

The DeLOCK 12455 is a 50 Ω omni-directional multiband antenna with an SMA male connector, designed for outdoor use. It integrates two PIFA antennas for LTE and GSM/UMTS and a GPS patch antenna for GNSS reception. The antenna has a compact form factor (height 65 mm, diameter 144 mm), weighs 1.2 kg and is protected against water and shocks for operation in demanding environments such as transportation, forestry, agriculture, construction and maritime applications.

Advantages

The antenna provides simultaneous cellular (LTE, GSM/UMTS) and GPS reception from three physically separate transmitting and receiving units, ensuring stable signal handling. Its omni-directional pattern offers uniform coverage in all directions, while the ruggedised, waterproof and shock-resistant housing supports extended temperature-range operation. The SMA male connector and 50 Ω impedance make it compatible with a wide range of radio equipment.

Suitable for

• Fleet and vehicle communications in transportation
• Remote monitoring and data links in agriculture and forestry
• Construction site connectivity
• Maritime tracking and GNSS-based navigation

How to use

Mount the antenna in a suitable outdoor location with clear exposure to the sky for optimal GPS reception and minimal obstructions for cellular signals. Connect the antenna to compatible equipment using the SMA male connector and ensure the radio device is configured for 50 Ω impedance. Secure the mounting to withstand shock and vibration according to the installation environment.

Recommendations

For best performance, place the antenna away from large metal objects and tall structures that can block signals; periodically inspect seals and mounting hardware to maintain waterproofing and mechanical integrity.
