To prevent lightning from taking out your transmitter board, you should tie two
4” loops in your twisted pair. These loops can be buried underground where
you exit the house. Before connecting your twisted pair to the transmitter, tie
these loops as if you’re tying a knot ( as shown below ). These will produce a
magnetic field when the lightning passes in between itself, thus causing it to
dissipate. Combined with Dog Guard’s built-in surge protection, the reduction
in voltage should keep the lightning from blowing out the transmitter board.

4. To cross driveways: Because cars and other heavy traffic cross here, install the
wire with extra care across driveways.
For gravel driveways:
•
Rake away stones to clear a straight line along which you’ll lay wire.
•
Dig a trench across the driveway between 3 – 4” deep.
•
Roll out the wire across the driveway. Use an old garden hose or other
nonmetallic tubing to run the wire through.
•
Lay this protected section of wire in the driveway trench.
•
Fill the trench and re-cover with gravel.
•
Continue to lay and bury the wire around the house.
