## **M1621HCT-SMA** 

## **Iridium Certified Antenna** 

## **Description** 

M1621HCT-SMA is a high performance antenna designed for the Iridium band, built on proprietary Maxtena HeliCore® technology. This technology provides exceptional pattern control, polarization purity and high efficiency in a very compact form factor. The M1621HCT-SMA is a screw-on design, featuring an integrated SMA connector. This product is ideal for applications requiring minimal integration effort or for retrofitting existing products. The design is equipped with an O-ring that makes the antenna waterproof once installed on a mating surface.
