What is the approximate maximum range for signals using transequatorial propagation?
- A.1,000 miles
- B.2,500 miles
- C.5,000 miles (correct answer)
- D.7,500 miles
WhyTransequatorial propagation can reach an approximate maximum range of 5,000 miles. Transequatorial propagation can extend out to roughly 5,000 miles under favorable conditions, well beyond the shorter distances typical of ordinary single-hop ionospheric skip, answer C. The shorter 1,000- and 2,500-mile figures undersell TEP's real reach, and 7,500 miles overstates its practical maximum range.
