  • 4kW power output
  • 48 NM Range
  • Plug and Play compatibility with Raymarine C-Series Widescreen, E-Series and G-Series multifunction navigation displays.
  • New and improved dome housing.
  • Improved radiation pattern and bearing resolution using Propagation Enhancing Geometry.
  • Advanced microprocessor controlled transmitter receiver features 8 Pulse width/PRF settings, providing enhanced targets returns though every range scale.
  • Improved sensitivity, signal to noise ratio, and a lower overall receive noise figure.
  • Same mounting pattern as previous generation radomes.
  • Utilizes small SeaTalkhs interconnect cable for ease of installation.
