	~~:'''E'''~~ is ~~the electric field strength in volts per meter~~

	~~:'''d''' is the distance~~ from ~~the radiator in meters~~

	~~Field strength meter is actually~~ a ~~simple receiver~~. ~~After~~ a ~~[[Tuner (electronics)\|tuner]] circuit~~, ~~the signal is detected~~ and ~~fed~~ to ~~a [[microammeter]]~~, ~~which is scaled in '''dBų'''~~. ~~The frequency range of the tuner is~~ usually ~~within the terrestrial broadcasting bands~~. ~~Some FS meters~~ can ~~also receive satellite ([[TVRO]] and RRO) frequencies~~. ~~Most modern FS meters have [[audio frequency\|AF]] and [[Composite video\|VF]] circuits and~~ can be ~~used as standard receivers~~. ~~Some FS meters are also equipped~~ with ~~printers to record received field strength~~.
