Abstract :
This paper describes the advantages and disadvantages of differential feeding of an antenna for low-frequency radio astronomy in the context of the SKA-low telescope. A series of practical measurements to test the correct functionality of the antenna + differential amplifier pair are described and results are presented and discussed.
