VHF Signal coverage: (Central Bohemia)

This picture shows the example of the VHF field strength coverage calculation of the transmiter placed on the roof of the building working on the frequency 145 MHz with output power of 100W comming to the omnidirectional antenna with 0 dBd gain. Calculation was made using 3D digital model of terain in raster of 100m. This picture shows the area of the Central Bohemia arround the Prague. See also a second picture showing the Coverage in whole Bohemia. The real field strength and covered area will be greater due to the usage of directional antenna on this band.
