The em-trak S300 provides you with reliable, high performance VHF antenna sharing capability. With the S300 a single VHF antenna can simultaneously support the full operation of your AIS transceiver, VHF radio and FM radio.

After fifteen years of creating marine electronics products we understand the environment within which our products must operate. The S300 is a single small unit which is simple to install and use and has been specifically designed, engineered and manufactured for long term continuous use in even the most extreme marine environments.

The S300’s core technology enables it with superior performance which translates into zero performance loss for the connected devices. The S300 is an ideal complement to a good quality Class B or Receiver where there is an existing VHF antenna available currently used for your VHF radio.
