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.

Model : MA-700

Concinnity and Solid Design for GPS Marine Antenna with Advanced Technology

Description :

MA700 is designed for the marine vessels mast or tall buildings that require long extra cables without signal constraint to the GPS receivers. MA700 is not only hidden in a durable and waterproof cover, but also cable is protected by a base which can prevent damage. The special design for MA700 is really delicate, compact and reliable. Besides that have concinnity and compacted design for base. It is the integration of the high performance GPS patch antenna and a low noise amplifier into an extremely fully waterproof enclosure and when connected to a GPS receiver with 2.5~5.5V DC antenna power, it can provide excellent antenna signal amplification and out-band filtering with rejection for that receiver at 3V DC or 5V DC input voltage.
