ABSTRACT:
A site reference source acts as a programmable frequency source. The site reference source includes a symmetrical radiating unit. The symmetrical radiating unit includes a cylindrical shaped structure, a signal generator, a power source and an antenna. The signal generator is housed within the cylindrical shaped structure. The power source is also housed within the cylindrical shaped structure. The power source provides power to the signal generator. The antenna is external to the cylindrical shaped structure. The antenna is electrically connected to the signal generator housed within the cylindrical shaped structure. In order to radiate signals, the signal generator generates signals and transmits the signals through the cylindrical shaped structure to the antenna.
