2J7B26JB-C177N-B16J “BIG MEDUSA Series“ antenna
€130,00 EUR
The 2J7B26JB is a High Performance, superb RHCP, omnidirectional IRIDIUM antenna for satellite communication around the World. Lightweight, ground plane independent passive antenna with 2.7 dBi Peak Gain and Axial ratio below 3 dB. Heavy Duty IK09 and water resistant IP67 and IP69 for all marine and land environments. Various mounting options for screw and pole mount installation.
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.
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.

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.
