Info
This section will collect information about all types of antennas and RF connectors used in AVM hardware. Each type gets an own article, which is linked from the Interfaces secftions of all Box-Models and Accessories articles, forming a cross reference database and the typical Model-Matrix per item.

Wave-Length[edit]

Wave length (full-wave / half-wave / quarter-wave):

  • 5GHz: 59.96 mm => 60 / 30 / 15 mm
  • 2.4 GHz: 124.91 mm => 125 / 62 / 31 mm
  • 1.9 GHz: 157.79 mm => 158 / 79 / 39 mm
  • 100 MHz: 3 m => 3000 / 1500 / 750 mm

AVM uses quarter-wave for internal antennas.

TODO[edit]

  • Find out AVM PCB numbers for 7150 DECT pcb mounted antennas
  • Find out the model of the 7590 on PCB stamped metal Airgain antenna
  • Get better 3390 pics, also from all on and offboard antennas
  • Make 3490, 5490 pics
  • Get 6820, 6850, 6890 pics
  • Get 6842 PCB back pics and opened sheildings
  • Distinguish different 5530 revisions (antenna connectors)
  • 5590 Interfaces
  • 5530 versions, see here
  • 6850 LTE + DECT interfaces
  • Find a 6430, *6460*
  • FX: The 3390 has 2x IPEX 2.4G + 1x Hirose 2.4G + 3x Hirose 5G, all single band
  • FX: The 3490 has, bessides the 3x IPEX, 2 Murata for 2.4G and 5G each
