Designed for a variety of applications including military and commercial usage, our multiband antennas offer multiple operating frequencies within a single housing. Where space is limited or constrained on a platform this allows one antenna to cover the job of two or more single band antennas. 

Multiband antennas differ to broadband antennas by focussing on specific common use frequency ranges, improving performance in those bands.
