A TV transmitting antenna is mounted at the top of a tower of height 175 m. Taking the radius of the Earth as $6.4\times10^{6}$ m, calculate the maximum line-of-sight range up to which the transmission can be received on the ground.

**Formula.** For a transmitting antenna of height $h$ alone (receiver at ground level), the maximum line-of-sight range is $d=\sqrt{2Rh}$, where $ …

Concept understanding — Space Wave and Line-of-Sight

A space wave travels in a straight line directly from a transmitting antenna to a receiving antenna, and it is the mode responsible for line-of-sight (LOS) communication, television broadcast, microwave links, and satellite communication. Above roughly 40 MHz, communication is confin …
