                         Observations (BINGO) telescope is a 40-m class radio telescope 
                         under construction that has been designed to measure the 
                         large-angular-scale intensity of HI emission at 9801260 MHz and 
                         hence to constrain dark energy parameters. A large focal plane 
                         array comprising of 1.7-metre diameter, 4.3-metre length 
                         corrugated feed horns is required in order to optimally illuminate 
                         the telescope. Additionally, very clean beams with low sidelobes 
                         across a broad frequency range are required, in order to 
                         facilitate the separation of the faint HI emission from bright 
                         Galactic foreground emission. Using novel construction methods, a 
                         full-sized prototype horn has been assembled. It has an average 
                         insertion loss of around \−0.15 dB across the band, with a 
                         return loss around 25 dB. The main beam is Gaussian with the first 
                         sidelobe at around \−25 dB. A septum polariser to separate 
                         the signal into the two hands of circular polarization has also 
                         been designed, built and tested.",
