DVB-T radiomobile coverage around Saint-Pern transmitter — R4 multiplex — channel 49 (698 MHz)

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

- Transmitter information:
— Saint-Pern — ground height = 178 m — pylone height=271 m
— By = 100 KWatts
— Antenna normalised 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:
— monopoly antenna mounted on a vehicle hr=1.5 m (see datasheet in CSV section)
— Antenna gain estimated by “double weighing” = + 5.9 dBi (see EXCEL section)
— vehicle positions collected by USB 65-channel GPS Data Logger (see datasheet in GPX section)
— Spectrum analyse: RF explorer (noise level = -115 dBm)
— Frequency band: 693-703 MHz, 112 values
— all measured values lesss than noise+ 3 dB (i.e. -112 dBm) are removed from files

- Roads information:
— zone of ille-et-vilaine and coasts of 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...
