ABSTRACT:
The unitary cellular telephone antenna includes a junction box to which is mounted both the antenna element, preferably a 5/8 wavelength antenna, and two 1/4 wavelength downwardly oriented radials to establish the antenna's ground plane. Electrical elements are included within the junction box to match the impedance of the antenna system to the cellular telephone transceiver and to maximize the radiated signal.
