Expression for radio horizon in km is ____(a) \(4.12(\sqrt{h_t}+\sqrt{h_r})\)(b) \(4.12(\sqrt{h_t}-\sqrt{h_r})\)(c) \(3.56(\sqrt{h_t}+\sqrt{h_r})\)(d) \(3.56(\sqrt{h_t}-\sqrt{h_r})\)The question was asked by my school teacher while I was bunking the class.My doubt stems from Space Wave Propagation topic in section Space Wave Propagation of Antennas |

Answer» RIGHT choice is (c) \(3.56(\sqrt{h_t}+\sqrt{h_r})\) To EXPLAIN I would say: Radio HORIZON is the point to which a space wave can reach MAXIMUM. Expression for radio horizon in km is \(d = 3.56(\sqrt{h_t}+\sqrt{h_r})\) Expression for the LOS distance is \(d = 4.12(\sqrt{h_t}+\sqrt{h_r})\) in km. |
