DVB-T radiomobile coverage around Saint-Pern transmitter - multiplex R4 - channel 49

- transmitter information :

  • Saint-Pern - ground height = 178 m - pylone height=271 m
  • PAR = 100 KWatts
  • Antenna normalized directivity pattern is estimated from a 10 km flat open space measurement as : G(elevation) = - 1.5 * |elevation| in dB. If G<-30 dB, G=-30 dB (when elevation > 20°). Elevation = angle in degrees with z axis

- receiver information :

  • monopole antenna mounted on a vehicule hr=1.5m (see datasheet in CSV section)
  • antenna gain estimated by "double pesée" = +5.9 dBi (see EXCEL section)
  • vehicule positions collected by USB 65-channel GPS Data Logger (see datasheet in GPX section)
  • Spectrum analyser : RF explorer (noise level = -115 dBm)
  • frequency band : 693-703 MHz, 112 values
  • all measured values less than noise+3dB (i.e. -112 dBm) are removed from files

- roads information :

  • zone of ille-et-vilaine et cotes d'armor departments of France
  • about 621K points
  • about 848 kms
  • in order not be in the coverage a small DVB-T emitter (less than 1 watt that can be identified on www.cartoradio.fr), we avoid to get into Rennes, Dinard, Saint-Malo ...
