Underground fence wires will need to form a loop to function properly.
Generally, underground electric fencing kits will come with layout options you can base your installation off of.
Boundary wires will need to be buried in the perimeter of the selected area and the wire needs to form a closed loop with the ends connected to the fence transmitter.
We recommend planning your installation before purchasing a specific underground fence kit to ensure you have selected a kit that works best with your property.
