The SB-202/2 is a dual UHF antenna used for high power applications in the 225 to 400 MHz frequency band. It provides broadband, omnidirectional coverage over the 225-400 MHz frequency band. It is designed for shipboard installations which are exposed to an extreme marine environment.
The totally fiberglass-enclosed radome protects the elements and feed network from the marine environment. The element assembly is secured within the radome to eliminate resonant vibration frequencies and to withstand the shock test requirement. The SB-202/2 is designed to withstand the MIL-S-901 shock test and the MIL-STD-167-1 vibration test.
