The 21-40-30 is a wideband, low profile antenna intended for data link and upper frequency JTRS applications. Unique, inverted discone design provides extremely wide frequency range within a maximum VSWR of 2.5:1.

Housed within a low loss, high strength radome the antenna elements are DC grounded for voltage transient protection and are foamed-inplace to ensure reliability in world wide conditions of military service. The low profile and rugged construction of this antenna makes it suitable for both airborne and ground installations.
