  We probed for Radio Frequency Interference (RFI) for the three potential
Galactic Emission Mapping Experiment (GEM) sites at Portugal using custom made
omnidirectional disconic antennas. For the installation of a 10-meter dish
dedicated to the mapping of Polarized Galactic Emission foreground planned for
2005-2007 in the 5-10 GHz band, the three sites chosen as suitable to host the
antenna were surveyed for local radio pollution in the frequency range
[0.01-10] GHz. Tests were done to look for radio broadcasting and mobile phone
emission lines in the radio spectrum. The results show one of the sites to be
almost entirely RFI clean and showing good conditions to host the experiment.
