Satellite Antenna DELOCK Navilock 12457 28 dBi Gain 14.4 cm Diameter

The Navilock multi-band satellite antenna DELOCK 12457 combines three physically separate transmit/receive units in a compact housing with a diameter of 14.4 cm and a height of 65 mm. It integrates a GPS patch antenna for GNSS reception and two PIFA elements dedicated to LTE and GSM/UMTS, delivering a maximum gain of 28 dBi and a VSWR of 2. The antenna is designed for outdoor use and comes in black.

Advantages

The antenna provides multi-band coverage (GPS/GNSS, LTE, GSM/UMTS) from three discrete elements, enabling simultaneous reception and transmission across these services. Its compact 14.4 cm diameter housing and 28 dBi maximum gain support effective satellite signal reception while the VSWR of 2 indicates matched performance. Built for outdoor environments, the unit is waterproof, shock resistant and rated for an extended temperature range.

Suitable for

• Transportation systems (vehicle-mounted antennae)
• Forestry and agricultural equipment
• Construction machinery and remote sites
• Maritime installations and vessels

How to use

Mount the antenna on a suitable exterior surface or mast ensuring a clear view of the sky for GNSS reception and unobstructed exposure for cellular bands. Use the appropriate mounting hardware and cable assemblies compatible with your radio, modem or receiver. Route and secure cabling to prevent damage from movement or weather. Verify connectors and impedance matching with your equipment and follow device-specific installation instructions for optimal performance.

Recommendations

For best results, position the antenna away from large metallic obstructions and noise sources, orient it according to manufacturer mounting guidelines, and use quality, low-loss coaxial cables and properly torqued connectors to preserve the specified gain and VSWR characteristics.
