(5) Polarization effects over tropospheric scatter paths. The transmitted polarization is
generally preserved in tropospheric scatter operation paths. Experiments show that 90 percent of the
received signal has the same polarization as the transmitted signal. Tests also indicate there are no
appreciable differences in signal strength for horizontal, vertical, or circular polarization. Therefore,
polarization has no significant effect on signal strength provided the receiving antenna is oriented in the
same plane as launched by the transmitting antenna.
