                         Observations (BINGO) telescope is a new 40 m class radio telescope 
                         to measure the large-angular-scale intensity of HI emission at 
                         980-1260 MHz to constrain dark energy parameters. As it needs to 
                         measure faint cosmological signals at the milliKelvin level, it 
                         requires a site that has very low radio frequency interference 
                         (RFI) at frequencies around 1 GHz. We report on measurement 
                         campaigns across Uruguay and Brazil to find a suitable site, which 
                         looked at the strength of the mobile phone signals and other radio 
                         transmissions, the location of wind turbines, and also included 
                         mapping airplane flight paths. The site chosen for the BINGO 
                         telescope is a valley at Serra do Urubu, a remote part of Paraiba 
                         in North-East Brazil, which has sheltering terrain. During our 
                         measurements with a portable receiver, we did not detect any RFI 
                         in or near the BINGO band, given the sensitivity of the equipment. 
                         A radio quiet zone around the selected site has been requested 
                         from the Brazilian authorities ahead of the telescope
