Invisible Dog Fence

While visiting family over Thanksgiving, my dog sitter let me know that an alarm was sounding in my garage. It turns out that alarm was the controller for our invisible dog fence (this is the one we have if you are interested https://www.amazon.com/Underground-Electric-Dog-Fence-Premium/dp/B00ZRPGLOC), stating that there was break in the wire.

A little explanation of how invisible dog fences work, skip ahead to the next paragraph if you are already familiar with the idea… The controller sends an RF signal down the wire which basically acts like a low power transmit antenna. From the controller, you can increase the RF power on the wire which makes the boundary line “thicker”, ie more distance on either side of the wire in which the dog will be shocked. The dog wears a collar that acts as a receiver for the signal, if the dog gets too close to the wire and the collar detects the signal, they will receive a shock. There are some additional features like adjustable correction levels, but that’s the basic idea of how they work.
