The electronic invisible fence d-fence works on the principle of connecting a transmitting energizer and an installed antenna wire that sends a signal to a receiver attached to the dog's collar. The energizer and the dog collar can be purchased separately.
The transmitting generator for the invisible fence d-fence 101 and 1001 is one of the power supply options for the invisible fence installation. It is a cheaper option without a backup power supply. It is suitable for powering areas up to a maximum of 9 hectares.
The other option is the d-fence 202 and 2002 broadcast generator, which has a battery backup power supply. It is designed to supply power for fencing larger plots of land, due to its higher power output. The generator is equipped with a large LCD display where all the necessary information is shown.
You can purchase a collar for another dog to go with the invisible fence. The number of dogs with the receiver attached is not limited within the enclosed area.
