CTPhone 1900 System Planning
For best results, position receiver and transmitter antennas so they have
the same polarization (Figure 2-8).
Figure 2-8. Antenna Polarization
Multipath Effect
All metallic materials reflect RF energy, creating conditions for multipath
interference. RF energy reflects at a 180° angle from the arriving wave.
This creates a condition where reflected signal waves arrive from many
directions at many different angles, which disperses the original signal
