Troll Systems, the Data Link Experts, supplied dual-polarized 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-polarized coaxial sleeve dipole and a horizontally-polarized 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.
Troll manufactures marine-qualified omnidirectional and long-range, tracking antennas, that are available in diversity and multi-band configurations. Troll Systems can also customize antennas to transmit and receive in a single frequency band, or on up to four frequency bands simultaneously, from 300MHz to 15GHz.
