Tri-Band GSM Antenna


The OMNI-A0075 is a tri-band omni-directional GSM antenna that has been designed for transmitters used to suppress radiocontrolled improvised explosive devices (RCIEDs) signals and convoy protection. This antenna incorporates a spring which allows it to bend up to 70 degrees as the wearer moves through doorways or under obstacles. The OMNI-A0075 has an omni-directional azimuth pattern with a low level of ripple to ensure all-round protection and an elevation pattern that shows no pattern break-up. This antenna is rated for 50 W indefinite continuous duty power handling. The OMNI-A0075 is lightweight yet immensely durable and is ideally suited to challenging conditions be it on a man portable device or a vehicle mountable device. Similar products: OMNI-A0134 is an extended version to reduce radiation hazard exposure. Total length increases to 710 mm.
