Wireless - Remote Controlled - Extended Commands Option

This WiFi Wireless Ham Radio Coax Antenna Switch allows a single transceiver to switch between 4 antennas or 4 transceivers to switch to a single antenna. (NOTE: the normally grounded model MUST NOT be connected to several transmitter or you risk permanently damaging it) 

The antenna switch comes with 2 separate modules: 

  • WiFi switch control module

  • Relays and connectors module

Having separate modules makes it more convenient to enclose the connectors in a metal box and the control in a small plastic box, the 2 modules are easily connected with 5 wires (wires not provided) via the screw terminal. 

3D printing files for connector and control module enclosures are available upon request.

Fully configurable via a web browser (SSID of router and password)

The standard firmware module  responds to simple TCP commands: 1,2,3,4 or a simple html command from your browser:"relay number" 

The status of the switch can be requested via a web browser command (the status is displayed as a simple JSON string):

The extended commands module (optional) responds to many more commands such as:

n  or sn: turns switch n  ON and all others OFF

+n : turns switch n ON leaving all other switches untouched

-n : turns switch n OFF leaving all other switches untouched

tn : toggles switch n (ON if OFF, OFF if ON)

g : turns all switched OFF (grounds them if the connector board supports grounding on OFF position)

Screw connectors on both boards. 

Requires wires to connect the control unit to the relay/connector board (wires not provided).
