Troll Systems, a data link expert, recently supplied dual-polarised omnidirectional antennas to the Royal Australian Navy (RAN), that were specifically designed to be deployed on ANZAC-class frigates.

Each antenna is comprised of two elements, a vertically-polarised coaxial sleeve dipole and a horizontally-polarised turnstile slot. Both elements are combined in a marine qualified, solid enclosure, that is tested to Mil-S-901D. Each enclosure is also engineered to meet an IP65 standard that guarantees optimum survivability even in the most demanding marine environments, according to the company.

Troll manufactures marine-qualified omnidirectional and long-range, tracking antennas, that are available in diversity and multi-band configurations. Troll Systems can also customise antennas to transmit and receive in a single frequency band, or on up to four frequency bands simultaneously, from 300MHz to 15GHz.
