field strength contours on this map represent average values
with the E.R.P. indicated; variations of as much as 3:1 in field
strength may occur at individual points especially in hilly or
built-up areas. The 0.1mV/m contour
should not be interpreted as a rigid boundary of the area
served, since the quality of reception obtainable would have
depended on local conditions. Fading and interference may at
times have been experienced in the outer areas served and also,
in difficult locations, nearer the transmitter. |
