PRODUCT DESCRIPTION

DMC50-17

  • Enhanced Corona Threshold: Engineered to suppress high-voltage corona discharge at altitudes, ensuring clear signal transmission in thin air.

  • Corrosion-Resistant Materials: Constructed from anodised aluminium and stainless steel hardware to resist salt spray and environmental degradation.

  • Low-Drag Aerodynamic Profile: Slim blade design minimises aerodynamic drag and fuel burn impact, crucial for long-range operations.

  • Omnidirectional Coverage: Uniform 360° horizontal radiation pattern provides consistent VHF signal reception and transmission without orientation sensitivity.

  • Backup or diversity antenna on multi-radio installations to enhance communication reliability.

  • Retrofit programs are replacing outdated rod antennas with low-drag blade designs.

  • General aviation upgrades are seeking factory-grade, high-performance VHF antenna solutions.

  • Onboard testing benches and flightline spares for immediate transceiver support.

  • How is the antenna mounted?

It uses a C-female bulkhead connector and standard blade mount provisions, typically on the fuselage or vertical fin.

  • Can it handle high-power transmissions?

Yes, it’s rated up to 1 kw continuous wave (CW), compatible with all standard VHF comm radios onboard commercial jets.

  • Is it compatible with other OEM blade antennas?

The DMC50-17 series is drop-in interchangeable with many ARINC-standard blade mounts used across Boeing and Airbus fleets.
