Dual-band systems are designed to provide consistent performance by providing the option to operate on two frequency bands with fast, automatic switching between them.
Where smartphones, laptops and tablets are concerned, dual-band routers commonly operate on the 2.4GHz and 5GHz bands. Dual-band antenna systems for maritime use, meanwhile, feature VSAT configurations such as C-band (4-8GHz) and Ku-band (12-18GHz), or Ku-band and Ka-band (26.5-40GHz).
In this context, marine-stabilised antenna systems such as Cobham SATCOM’s Sea Tel 9797B (available as a dual-band selectable C- and Ku-band system) and Sea Tel 9711 IMA system with C/Ku switchable feeds offer flexibility and stable connectivity irrespective of location and prevailing sea and weather conditions.
Sea Tel dual-band antenna systems are designed to provide the flexibility to retain high-speed connectivity and high quality voice communication when an i.e., Offshore Support Vessel is moved from one region to another for a new project. Likewise, dual-band antennas are applicable to vessel is in transit, moving from one coverage type to another.
While dual-band hardware can require more Capex than single-band equivalents, Opex is significantly lower through the breadth and versatility of services, and the fact that engineers do not need to visit a vessel to switch the antenna to a different operating frequency.
