abstract = "The Baryon acoustic oscillations from Integrated Neutral Gas
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
construction.",
