UHF Satcom

The 21-30-76 is a rugged UHF and Satcom antenna designed for airborne, ground and shipborne applications. A high strength aerodynamic vertical shell houses a 225 - 512 MHz linear element that can be used for UHF line of sight “LOS” communications or UHF Satcom at low angles of elevation. This vertical shell also supports a “Bat-Wing” shape horizontal element containing a pair of cross dipoles, connected to provide high angle, right hand circularly polarized UHF Satcom coverage. 

  • Aerodynamic design
