Figure 4.19 A typical rectangular footprint for a mounting angle of 15°

Figure 4.20 A typical rectangular footprint for a mounting angle of 90°

The guaranteed rectangular footprints for various number of carriers, mounting heights and

mounting angles can be found in section 12.5 . The height is the distance from the reception

plane and not from the floor.

Guaranteed rectangular footprints can also be calculated with the footprint calculation tool

(available on the documentation CD-ROM). The given values are for one radiator only, and

therefore do not take into consideration the beneficial effects of overlapping footprints. The

beneficial effects of reflections are also not included. As rule of thumb can be given for

systems with up to 4 carriers, that if the receiver can pick up the signal of two adjacent

radiators the distance between these radiators can be increased by a factor 1.4 approximately

(see Figure 4.21).
