  • Low Drag and Light Weight
  • Fully Sealed and Meets MIL-STD-810 Environmental Conditions
  • Excellent Omnidirectional Radiation Pattern
  • N-type Female Connector
  • Grounded for Lightning Protection
  • High Power Capability
  • Rugged aluminum construction
  • Suitable for aircraft operating up to Mach 2.5
