Since the circularity / axial ratio of the downlink\nantennas is very good (the uplink is somewhat worse), listening on the\nopposite circular polarization (provided that you use circular\nantennas on your side of course) may wipe out the signal completely:)\n\n73 & hope to work you soon via DO-64\n\nWouter PE4WJ\n", "attachments": [] }
