Abstract
A battery powered radio transmitter of a cross-sectional diameter substantially equal to the cross-sectional diameter of an arrow shaft is positioned in series between the head and nock of a metallic hunting arrow. The transmitter section of the shaft is light in weight so as not to affect the normal flight characteristics of the arrow. The shaft portion between the transmitter and the nock acts as the antenna for the transmitter. A switch is provided for operation of the transmitter. A portable directional radio receiver of the same frequency as the transmitter is utilized by the hunter to track the spent arrow.
Claims8
In a metallic hunting arrow of the type comprising a shaft carrying a removable arrowhead at one end thereof and a nock at the other end thereof for driving the arrow, said arrow having an improved locating means comprising:
- a miniaturized battery powered radio tramsitter, positioned intermediate said arrowhead end and nock, said transmitter is enclosed within a cylindrical housing substantially equal in cross-section to the shaft and forms an extension thereof and the shaft portion between said transmitter and said nock acts as the radiating antenna for said transmitter.
A method for tracking a metallic arrow with an arrowhead at one end and a nock at the other end of a shaft fired from a bow which comprises the steps of:
- connecting a battery-powered radio transmitter including an antenna, said transmitter having a cross section substantially equal to the cross-section of said shaft in series between said arrowhead and said shaft forming a continuation of the length of said shaft;
- shooting the arrow in the direction of the intended target a portion of said shaft of said arrow is connected to said antenna whereby said shaft transmitts a radio signal;
- and
- tracking said signal by a radio receiver tuned to the signal frequency of said transmitter, with said receiver having a Directional Antenna to permit the direction of the transmitted signal to be detected and observed.
In a hunting arrow having a metal shaft carrying an arrowhead at one end thereof and a nock at the other end thereof comprising:
- A battery operated radio transmitter positioned in series between said arrowhead and said shaft, said transmitter having substantialy the same circumference as said shaft and is sufficiently light in weight and the shaft acts as a transmitting antenna and the expected aerodynamics and stability of the arrow are maintained.
