Two aerials are 2.50m apart, and both are receiving the same radio signal with a frequency of 125MHz. The phase difference between them is measured as 114∘.
Calculate the path difference between the two aerials.
The aerial which receives the radio signal first is directly North of the one which receives the signal slightly later. What are the possible bearings of the transmitter from the receiving aerials? You may assume that the transmitter is many kilometres from the receiving aerials, and therefore that the path of the waves travelling to the two receivers are effectively parallel when measured in the vicinity of the receiving aerials.
