Abstract :
The Arabian Gulf is characterized by extremely anomalous tropospheric electromagnetic wave propagation effects, most of which defy traditional Earth `bulge´ obstruction phenomena. In February at noon one may receive a signal (VHF-UHF) from Kuwait or Muscat (Oman) at distances of 425 and 700 km respectively. To investigate the feasibility of a Gulf Cooperative Countries (GCC) inter-communication TV transmission in the VHF-UHF bands, during 1986-90 the author has been observing and recording the signal levels of some distant TV stations. The state of Bahrain is the receiving site. The regional topography and meteorology, as related to a possible reliable inter-communication TV transmission in the Gulf area are considered. The characteristics of received signal levels in relation to diurnal variations, seasonal variations and annual variations are described, including the system reliability in terms of mean signal level deviations
