Industry-Leading Performance and Robustness for Marine Applications
2J Antennas is expanding its “Big Medusa'' series by adding the new high performance heavy-duty Iridium Quadrifilar Helix (QHA) antenna (2J7B26JB-C177N-B16J). This industry-leading passive antenna provides superior connection to the Iridium network with a high peak gain of 2.7 dBi in low elevation angles while maintaining a 86.4% efficiency (far above the industry standards). This helical antenna is unique in its simplicity of design and has an extremely low axial ratio below 3 dB that optimises the circular polarization and delivers superior performance worldwide.
Big Medusa is a simple solution to the problem of non geosynchronous satellite connections where most antenna designs focus on extended range, receiving signals over large arcs, but having null spots directly overhead or at other inopportune locations. Extremely robust and waterproof, this design was developed for marine applications where reliability and mission critical communications are the number one priority during extreme weather conditions.
Suggested applications include:
- Iridium voice and data applications
- Marine
- Boats, Yachts and Ships
- Public Safety/ Coast Guard
- Mission Critical Communication
- Law enforcement and public safety
- Satellite Communication
The omnidirectional radiation pattern brings a full spectrum of signal quality within the 1621 MHz band and with superior RHCP rejecting multi-path interference and optimising signal strength making it the ideal choice for marine environments.
Installation / Environmental
This durable and waterproof antenna is fully IP67, IP69 and IK09 certified offering resistance to water, dust and impact making it the number one solution for extreme weather conditions. The robust housing and base are manufactured with commercial grade ASA material. The antenna dimensions for the pole mount is Ø 96 x H200 and Ø 96 x H 131 for the screw mount configuration.
The 2J7B26JB-C177N-B16J offers various configurable anti-rotation mounting options that include pole with maximum Ø 43mm and screw mount with maximum 7mm surface thickness. As with all ground plane independent antennas, this system can be installed on any surface type with minimal restrictions.
Choosing the right antenna for the right job is important and our highly skilled engineers are available to assist with antenna selection and/or any customisation needs. Our products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
