Testing a homebrew 6el Yagi with no preamp directly connected via 2m coax cable to a DVB-T dongle used as cheap SDR. Nice signal strengths from UHF military satellites. These data streams are around 244 MHz. There are various downlink signals in the 240-270 MHz range. These are only used as test signals since they are highly encrypted and cannot be decoded, of course... For more information and a frequency lists please see PJ Marsh's website: www.uhf-satcom.com
