KGEA-HBB KGEA-HBB Short Range Antenna LF for smart entry system. External housing + LPM (cover) 

KGEA-HBB Short Range Antenna LF for smart entry system. External housing + LPM (cover)

PREMO is developing customized door handle antennas using a type of technology over-molding low pressure depending on themechanical requirements and waterproof IP degree required by the customer.

For Door Handle Antennas, we also have the ability to integrate in a unique connector (6ways), the Antenna LF + Switch + LED as a single whole.


  • Short antenna (length until 150 mm).
  • External housing shape H-bridge Material PBT-GF30% or PA66-GF30%
  • Strong anchor points which provide an easy assembly and will ensure mechanical robustness
  •  Higher impact absorption and mechanical reduction preventive.
  • LF antenna module inside external housing is to cover by Low Pressure Technology ( PM)
  • LPM is a well know technology in PREMO.
  • Very fast to produce (No Curing needed)
  • IP56 grade Waterproof
  • Connector Waterproof located outside assembly housing plastic base.
  • High stability in temperature (-40ºC up to +85ºC).
  • Resonant frequency adjusting below +/- 2kHz.
  • Custom L-C value (F-Resonant)
  • This antenna is designed based on AECQ-200.
