Antenna Description

169MHz ISM-ERMES High Frequency, Compact and ERMES Compatible Dipole Antenna

The 169 MHz ISM ERMES is the best-suited dipole antenna for wireless metering within ISM / ERMES / VHF standards (169.4-169.9 MHZ frequency range) as an alternative to higher frequencies. With linear polarization, this antenna is highly suitable for longer-range applications while operating at low power. It operates with a very high frequency even amidst an urban environment. This omnidirectional antenna is ideal for devices and sensors that are placed in hard-to-reach places, such as basements or metal cabinets where propagation conditions are poor. This is because the 169 MHz band allows for good RF performance in terms of building penetration, coverage, and consumption of battery. 

Suggested applications include:

  • Smart meters 
  • Industrial remote control
  • Smart home 
  • Smart cities
  • Survey devices 
  • Industrial IoT

Installation / Environmental

With a slim and compact design and dimension of Ø 13.6 × 168 mm, this antenna can be installed in places where space is restricted. The SMA-Male connector mount and dipole topology allow for easy direct installation. The 2JD0819 is ground plane independent, eliminating any grounding restrictions during the installation process. Its optimal operation parameters are within temperatures of -40C to +85C.  All our products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
