A comparative study of the commonly used methods for the predlctlon of the coverage area due to transmitter operating at the HF band is presented. Those slatlstlcal model-based tools are Ionospheric Communication Analysis and Prediction Program; IONCAP, Ionospheric Communication Enhanced Profile Analysls and Circuit Prediction Program; ICEPAC, Voice of America's VOACAP and ITU's REC 533, and those are illustrated by computing the coverage area of a typical transmitter located at Oxford-England operating at 13399 MHz (HF Band I). Later, those results are compared with the experimental data measured at Istanbul-Turkey for a transmitter located at Oxford-England. Finally, the same problem Is analyzed by the ray-traclng technique using the experimental data. The advantages and the disadvantages of the methods are discussed.
