NATEC’s RNS216M extends this traditional switching function to Ethernet. Up to six HF and 50 MHz antennas can be connected and selected either with the local rotary switch or remotely from a web browser on the LAN. No dedicated client application is required. Another important feature is its GND connection function. Unselected antenna ports are connected to ground, and all ports automatically return…
