	~~[[File:Earthbulge.jpg\|frame\|'''R''' is~~ the ~~radius~~ of the ~~Earth, '''h''' is the height~~ of the ~~transmitter (exaggerated), '''d''' is~~ the ~~line~~ of ~~sight distance]]~~
	~~Assuming~~ a ~~perfect sphere with no terrain irregularity,~~ the ~~distance~~ to ~~horizon from~~ a ~~high altitude [[Transmitter station\|transmitter]] (i.e. line~~ of ~~sight) can readily be calculated~~.

	~~Let '''R''' be the radius of Earth~~ and ~~'''h''' be the altitude of a telecommunication station~~. ~~Line of sight distance '''d''' of this station is given by the [[Pythagorean theorem]];~~

	: <~~math~~>~~d^2=(R+h)^{2}-R^2= 2\cdot R \cdot h +h^2~~<~~/math~~>

	~~Since the altitude of the station~~ is ~~much less than the radius~~ of ~~the Earth~~,

	~~: <math>d \approx \sqrt{ 2\cdot R \cdot h}</math>~~

	The ~~mean radius of~~ the ~~earth is about {{convert\|6378\|km}}. (See [[Earth radius]]) Using the same units for both the altitude of~~ the ~~station~~ and the ~~radius of the earth~~,

	~~: <math>d \approx \sqrt{ 2\cdot 6378 \cdot h} \approx 112.9 \cdot \sqrt{ \cdot h} </math>~~

	~~If the height is given~~ in ~~'''m~~.'~~'' and distance in '''km'''.~~

	~~: <math>d \approx 3.57 \cdot \sqrt{h}</math>~~

	~~If the height is given in '''ft.''' and the distance in '''miles'''~~,

	~~: <math>d \approx 1.23 \cdot \sqrt{h}</math>~~

	~~== The actual service range ==~~

	~~The above analysis doesn’t take the effect of atmosphere on the propagation path of the RF signals into consideration. In fact~~, ~~the RF signals don’t propagate in straight lines. Because of the canalizing effects~~ of ~~atmospheric layers, the propagation paths~~ are ~~somewhat curved. Thus~~, ~~the maximum service range of the station~~, ~~is not equal~~ to ~~the [[line~~-~~of-sight propagation\|line of sight]] distance. Usually a factor '''k''' is used in the equation above~~

	~~: <math>d \approx \sqrt{2 \cdot k \cdot R \cdot h} </math>~~

	~~'''k > 1''' means geometrically reduced bulge~~ and ~~a longer service range~~. ~~On the other hand~~, ~~'''k < 1''' means a shorter service range.~~

	~~Experience has shown that, under normal weather conditions '''k''' is '''4/3'''.<ref>R.Busi: ''Technical Monograph 3108-1967 High Altitude VHF~~ and ~~UHF Broadcasting Stations'', European Broadcasting Union Brussels,1967</ref> That means that,~~ the ~~maximum service range increases by '''% 15'''~~
