The 2J7426MPz by 2J Antennas is a high-performance compact antenna certified for use with the Iridium satellite communication system. Manufactured from polycarbonate (PC) and acrylic-styrene-acrylate terpolymer (ASA), it offers strong resistance to UV, moisture, and heat for reliable outdoor operation.
Waterproof to IP69, the antenna is designed for harsh environments with frequent exposure to water, dust, and debris. The magnetic mount allows easy installation and removal between vehicles or assets, and can be converted to adhesive mounting for permanent installations. Delivered with a 3 m LL100 coaxial cable and SMA-male connector.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- IP67
- An ingress protection rating meaning the enclosure is dust-tight and can survive temporary immersion in water under specified test conditions. This matters when choosing a sensor for outdoor, wet, or wash-down environments.
- SMA
- SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.
