Russia Requires WiFi Registration
While WiFi wasn’t as broadly unlicensed in Russia as it is in most other industrialized nations, your can not find wifi antenna anywhere a state regulator exempted indoor use in certain bands from registration. The Mass Media agency apparently believes that it has the authority to compel this, although there’s some doubt by observers as to whether it really falls in their purview.

MA620P



Description


 

Small size and ruggedness, demand of vehicle locating and car navigation GPS antenna that will sustain harsh environment.

  • Low noise figure
  • Fully weather proof.
  • Ultra-high Sensitivity
  • Compact construction
  • Excellent temperature stability

The antenna system MA-620P is the integration of the high performance GPS patch antenna and a low noise amplifier into state-of-the-art low a very low profile/extremely compact/fully waterproof antenna signal enclosure. When connected to a GPS receiver with +2.5~ 5.5V DC antenna powers it provides excellent signal amplification and out-band-rejection for that receiver.

Features:
GPS antenna with double threaded bolts and through holes for cable routing with course & fine treaded pitch locking for wing-nut fastener and lock-nut to prevent vibrations and un-authorize removal.
