Hello!
This is my version of an external antenna for WMR200.
The antenna is made up of copper wire, assembled with a screw terminal block. Antenna length is 217 cm; cable length is more than 20 meters. Installed on a mast on the roof, near the weather sensors. To connect the antenna use a BNC connector.
Station is receiving data from Wind Speed Sensor - every
14 seconds, from other sensors - every 60 seconds (documentation as specified).
