Abstract
The present disclosure relates to an irrigation system comprising a surface wave launcher located predominantly underground and controlled by an electronic control system, and a surface wave receiver located underground and operatively coupled to an irrigation sprinkler. In operation, the surface wave launcher is activated by the electronic control system to, under predetermined conditions, transmit a surface wave signal. The surface wave signal is transmitted at a relatively low operating frequency and received by the surface wave receiver to activate the irrigation sprinkler.

25. An irrigation system comprising:
-
a surface wave launcher configured to be; (i) located predominantly underground, and (ii) controlled by an electronic control system to, under at least one predetermined condition, transmit a surface wave signal at a relatively low operating frequency; and a surface wave receiver configured to be; (i) located underground, and (ii) operatively coupled to an irrigation sprinkler to activate the irrigation sprinkler in response to the low operating frequency surface wave signal. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
