Overview
The patented Airmar GH2183 combines GPS positioning and highly accurate heading information in one compact antenna.
The GH2183 eliminates the need to install a GPS antenna above deck and a heading sensor below deck. Only one above-deck installation is required, saving installation time and money. The waterproof housing protects the internal components—all of which are solid-state (no moving parts). This means the GH2183 can withstand almost any condition that exists in the marine environment.
