GF 404/…

3 dB Mobile GlassFix® Antenna for the 450 MHz Band
Description
  • Collinear, 3 dB mobile antenna for the 450 MHz band using the GlassFix® mounting principle.
  • Mounting on car window glass – no holes required.
  • Double-adhesion procedure ensures fast and reliable fixing.
  • Internal matching unit feeds external antenna through window glass.
  • Half-wave collinear design – no ground plane required.
  • High positioning gives performance equal to conventionally mounted car roof antenna.
  • FME FastCabling system (cable to be ordered separately).
  • Simple tuning procedure by means of tuning screw on matching unit.
  • Easily removable whip for cleaning in car-washing machine
  • Swivel joint for 180° angle adjustment.
  • If removal of antenna installation is necessary, a quick dismantling procedure leaves no trace of the installation.
  • NOTA
  • GF antennas are not suitable for car models with windows having heat reflective coating.
