Abstract
A short, resonant top-loaded helical coil antenna having a flexible lower section is attached to one side of the housing of a receiver unit. The antenna is approximately eight inches in length, and extends outwardly from the receiver unit at an angle of about 30.degree. from vertical, so as to maintain a minimum spacing from the dog's neck.
