**ISM RF radiomobile coverage with low VHF antennas @145MHz in urban environnement (Saint-Malo)**

_**Transmitter :**_
- Baofeng talkie-walkie
- VHF in ISM band
- CW=145MHz with BW=25kHz
- Power = 1 Watt (30 dBm)
- omnidirectionnal monopole antenna (see in pdf)
- coordinates in Lambert-93 / NGF-93 datum (see in pdf)

_**Receiver :**_
- Spectrum analyzer : RF explorer combo 3G right sma port, noise level=-105 dBm
- omnidirectionnal monopole antenna (see specification in CSV section)
- all data less than noise+3dB (i.e. -101 dBm) are removed in files

_**Roads :**_
- town of Saint-Malo in France
- about xxx points
- about 150 kms
- in order not to be pertubated by intermodulation, as other VHF talkie-walkies can be used in the zone, a special filtering is proceeding to remove bad data when VHF radio coexistence occurs
