Antenna Description


Bringing the Most Accurate Positioning and Data/Voice Communication to the Global Market

To complement the Iridium antenna portfolio, 2J Antennas is adding the GPS/Galileo-Iridium Certified Magnetic Mount Antenna (2J7434MPz) designed for geo positional, mobile and data communication applications.  Designed to operate within the GPS, Galileo, QZSS and Iridium standards, this compact antenna is ideal for the automotive and transportation markets where accurate positioning and reliable data/voice communication is necessary.

Suggested applications include:

- Automobile/ Transportation
- Emergency response
- Tracking/ Mapping Devices
- Industrial Machinery


The 1575 MHz band is dedicated to GPS/ QZSS /Galileo and the 1621 MHz band is dedicated to Iridium while providing full range signal strength and signal quality with a hemispherical radiation pattern.


Installation / Environmental


The low-profile antenna housing, measuring Ø 54 × 14.7 mm, is manufactured with high quality polycarbonate (PC) and acrylic-styrene-acrylate terpolymer (ASA) that is resistant to UV, moisture, and heat. For optimal performance, the recommended operational and storage temperatures are -40C to +85C.

2J7434MPz comes with a powerful magnetic mount that is strong enough for long term applications but also offers the convenience of frequent relocation on any metal surfaces. In case adhesive mount required, antenna is equipped with double side adhesive sticker. For optimal antenna operation, we recommend the antenna is installed facing up towards the sky with an uninterrupted signal path.

Delivered with a standard SMA-Male connector and a 300 cm long LL100 cable that is tuned for excellent processing properties, outstanding coupling resistance, stable impedance, low signal attenuation and is approved by most OEM’s. Our team of experts is available to assist in customizing options by offering a wide range of alternative connectors for absolute customer satisfaction.

All our products are tested rigorously to ensure absolute antenna function in the most extreme conditions to achieve 100% customer satisfaction. 2J Antennas supports the health of our environment and all our products are manufactured without hazardous materials while maintaining full REACH and RoHS compliance. This antenna is IP67, IP69 and Iridium certified.
