Does the radio collar boundary wire have to be buried?
No. Your options are: 1/ bury it, 2/ leave on the surface, or 3/ attach to an existing fence, wall or other structure. The installation method is completely up to you. If you decide to bury the wire then 5cm or more is sufficient but no more than 20cm. If you attach wire to a fence it must be no more than 20cm above ground level.

How do I place the boundary wire cross a driveway?
For hard surfaces such as concrete, pavers, or bitumen, simply run the wire across the surface inside some protective polythene pipe (irrigation pipe). Boundary Wire Tie-Down Pegs might be suitable for securing the pipe. Concrete driveways have an expansion joint every 5m or so. You can often place the wire into this joint. On gravel driveways bury the wire inside hard PVC conduit.

Can I attach two boundary wires to the transmitter?
No. Wireless Dog Fence systems use just one wire. Any boundary shape you want to create can generally be designed with that single wire. See our Boundary Design Examples section below.

Can I use an existing boundary wire installation of another brand?
Possibly, depending on its age, condition and what materials were used. The Sureguard Boundary Wire Transmitter constantly checks and reports Boundary Wire breaks and whether transmission strength is below specification. So, install the transmitter and allow it to test your existing boundary.

I've read elsewhere you need to round off corners to stop signal cancellation. What does Sureguard recommend?
Rounding the corners of your boundary give very little benefit. The signal does not cancel on a Sureguard collar. However, because the distance is governed by the strength of the radio signal, i.e. stronger signal is interpreted as closer distance, you will see an increased activation distance at corners because the collar is detecting radio signal from two directions at once. This means your dog has less area to access at corners. If this is a problem and you have an existing fence then about 2m to 4m from the corner you should ramp the boundary wire up to the top of the corner then ramp the wire down in the other direction. Test the activation distance on the collar and adjust the height of the wire at the corner until you get a more even activation distance.

I have a narrow walkway between the fence and house wall. How do I stop the collar activating there because the dog is right next to the wire?
Obviously, the collar will activate wherever you place the boundary wire. Narrow section as you describe can be difficult to handle. Example #6 below shows one method of cancelling the signal in selected areas. Of course, if there is no radio signal there you have effectively created an opening in the boundary.

Can I install two boundaries with two transmitters?
Yes, but obviously your dog won't be able to cross from one containment area to the other without your help. You would need to lead him across the boundaries using the same technique as taking your dog for a walk. (see Radio Collar product page FAQ for more details).

What are signal anomalies?
In some situations, large metal objects can become energised by the radio signal possibly causing your dog's collar to activate where you did not expect. This issue is governed by physics not a particular brand. It is more prevalant on small properties. Here are some common scenarios: Sheds: A boundary wire is run behind a shed resulting in the collar activating at the front of the shed. Trampolines: A Trampoline near the boundary wire absorbs the radio signal causing the  collar to trigger directly under its frame. Cars: If the car is parked next to the boundary wire your dog's collar may activate around the car. Steel structures: Steel framed houses or a steel staircase may also absorb the radio signal if within close enough to the boundary wire. Footings: A single wire run along a house wall can transmit its signal through the steel footings to doorways on the other side of the house. Solutions: All these situations can be fixed by either 1/ moving the boundary wire further away from the steel object, or 2/ reducing the activation distance of each collar or 3/ change to a doubled wire boundary rather than a simple one (see examples below).
