The effect of radiation on the transmission line can be simulated by a 

 resistance R, 



K — — TT \ — 7^ — / ohms

shunted across the open end. This is not the resistance seen by the 

 generator. If V and / are the amplitudes of the voltage and the 

 electric current at their antinodes and Zq the characteristic impedance 

 of the coaxial pair, then 



F = Zo/ - (eoiog^W. 



(39) 



Since the end of the coaxial pair is a voltage antinode, the radiated 

 power may be expressed as 



W ^ 107r2('^V^' watts. 



(40) 



Hence the radiation resistance seen by a generator placed at a current 

 antinode is 



20^252 



Ra = 



X^ 



ohms.

With this simple illustration, we conclude the present paper.
