ABSTRACT:
A new and improved arrow tracking apparatus includes a radio transmitter assembly, attached to an arrow, for transmitting radio waves associated with the arrow. The radio transmitter assembly is in the form of a jacket that jackets a shaft of the arrow. A battery-powered hand-held receiver assembly is carried by a person for receiving radio waves from the radio transmitter assembly. The components of the radio transmitter assembly are distributed along the jacket, such that the arrow, equipped with the radio transmitter assembly, is well balanced so that the arrow does not wobble in its flight path. The jacket includes a substantially smooth surface, such that the arrow has both good dynamic flight characteristics and good aerodynamic characteristics. The radio transmitter assembly includes a transmitter unit and an antenna assembly, and the antenna assembly may include antennas in the form of barbs. The jacket includes a first jacket sub-unit and a second jacket sub-unit. The first jacket sub-unit and the second jacket sub-unit are adjustable with respect to each other along the shaft of the arrow such that optimal weight distribution along the shaft of the arrow can be achieved. The hand-held receiver assembly includes a handle portion and a directional antenna portion. The hand-held receiver assembly may include an output jack for headphones. The hand-held receiver assembly may also include a compass.
