The rang may be affected to some degree by barometric pressure and /or increased humidity which often gives greater ranges than normally attained. The atmospheric refraction results in the radio waves tending to follow curved rather than straight line paths. The bending or refraction arises from a change of wave speed as the wave propagate through the atmosphere, the waves changing direction towards the region of lower wave speed. The degree of bending or refraction depends upon the rate at which the wave speed changes. This is governed by the refractive index of the air and its variation with height which, in turn, depends upon the pressure, temperature and humidity of the air. Anther significant factor in determining rang is, generally, the height above sea level of the transmitting and receiving aerials. It should also be noted that the fact that a transmitter and a receiver are within radio sight does not automatically guarantee that an acceptable signal will be received at that point. Good reception will depend, amongst other things, on the power of the transmission, the sensitivity of the receiver and the quality and position of the transmitting and receiving aerials.51.

Which of the following statements is FALSE?A The antennas of transmitter or receiver will influence the VHF range.B The power of transmitter or receiver will influence the VHF range.C The height of transmitter will decide a little VHF range.D The name of identification of transmitter will slightly influence the VHF rangeEvery radio installation shall: 1.
