Show amount of power that your aerial picks up it has been computed that the amount of power picked up by tile the ordinary receiving aerial Is about one billionth of 0 9 ly power think of it I 1 if your receiver picked up ns as much power its as that possessed by a ly fly you would be receiving a billion times in more 0 re energy than you are now receiving it seems almost impossible to comprehend ahn fact here Is anther another illustration that may help you to understand how very small Is the power actually picked up by your antenna if the power radiated by the average transmitting station were collected and used to hent heat an ordinary electric toaster it would not even glow at a dull red client and certainly would not burn your bread yet this small amount of energy Is radiating in till nil directions and spreads over n circle a diameter of to miles for signals have been picked up hundreds of times at points to miles distant from the transmitting station just libia linas ine lne every foot of space in in a circle with a radius of miles being flooded yath ith part of the energy that originally was only enough to heat an electric toaster ton ster then you begin to got get no an iden of tit the extremely small amount of energy that reaches your particular aerial from this it will lio be realized that to detect the extremely faint signals from distant stations your recel receiver vr must be very sen etive and efficient edl effi clent |
