Abstract
An improved antenna system for a collar-mounted receiver-stimulator unit of an electronic animal training apparatus includes a conductive antenna mounting connector for detachable connection of an external flex antenna to the receiver-stimulator unit, a ferrite core, and a first winding on the ferrite core is coupled to a receiver circuit of the receiver-stimulator unit, and constitutes an internal ferrite antenna thereof. A second winding on the ferrite core is connected to the antenna mounting conductor and coacts with the first winding to function as a matching transformer between a receiver antenna input terminal and an external high flex antenna connected to the antenna mounting connector. The longitudinal axis of the ferrite core is co-planar with a longitudinal axis of the flex antenna.
