The orientation taken as a standard of comparison must 

 be such as to make the distance from oscillator to receiver 

 laro-e in comparison with the height of antenna. This 

 condition is satisfied sufficiently by taking 1° as the standard. 



It is difficult to draw any conclusions from these tables 

 for small orientations, owing to the lack of a reliable series
