My Garden is on Raised beds and the High Voltage wire is just 3 inches above the wood frames on homemade PVC Pipe Insulators. Could be Quite useful for persons that have Rabbit Problems also, with the wire raised a bit higher, But Read Warning Below. Definately Makes a STRONG Electric Fence. However, because it is a Continuous pulse output,
