An apparatus used in search and rescue operations that combines the features of a dragstick with the features of a radio antenna. The apparatus is comprised of an aluminum rod split into two, adjustably connected sections. At one end of the rod is a metal spike, The metal spike is used to make identifying marks in the ground thereby allowing the searcher to retrace his steps. At the other end of the rod is an electrical connector which allows the rod to be coupled to a standard two-way radio via coaxial cable. When current flows through the rod it acts like a half wavelength, omni-directional antenna. One of the two sections can be extended from or retracted into the other section, thereby varying the operating frequency of the rod when the rod operates as an antenna. An insulated grip allows the user to hold the rod while electrical current is flowing therethrough.
