Tri-Band GSM Antenna

OMNI-A0090
Active

The OMNI-A0090 is a tri-band omni-directional GSM antenna that has been designed to be used in high-powered transmit applications to suppress signals in applications like convoy protection and for RCIED. The design of this antenna allows it to bend up to 70° The OMNI-A0090 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.
