 if there would be any evidence obtained of the wave-length

being increased by inserting this inductance coil at the base of 

 the antenna. In this case the length of the conductor from D 

 to earth was 754-82 + 25 = 182 cms , though the inductance coil, 

 itself, would probably be equivalent to 200 cms of straight wire.
