So one has to findsome place with a nice view. The height of aerial will
determine how far signal will go, while the power of
transmitter will determine how strong the signal is
when somebody gets there.

  

If the user runs 100W into an aerial in his front room he’ll produce a super signal but only his neighbors will be privileged to hear it. Conversely a 5W Transmitter running into a good location could give you coverage of 5 miles (8 km) or more. Keep the aerial well anyway from anything else and above any obstructions like trees and chimneys. VHF radio waves do bend a bit so you’ll get a bit more coverage than one can see, but it’s hard to say how much. Following picture is a photograph of IIT RADAR Tank, which is the proposed site for FM Transmitting antenna and Base Station.
