Table 7.4: Calculation of the delay switch positions of a system with two transmitters
Systems with more than 4 carriers and a radiator under a balcony
The next figure illustrates a situation in which a radiation signal delay occurs and which can be
compensated for. For systems with more than four carriers, add one delay switch position per
10 meter (33 feet) difference in signal path length to the radiators which are closest to the
overlapping coverage area. In the next figure the signal path length difference is 12 meter. Add
one delay switch position to the calculated switch position(s) for the radiator(s) under the
balcony.
