For radiation pattern measurements VTT has two
anechoic test chambers:
 The larger one (dimensions of 12m*12m*17m)
operates in the frequency range of 100 MHz -
200 GHz.
 The smaller one (dimensions of 4.4m*4.6m*8
m) is electromagnetically shielded and it
operates from 500 MHz upwards.
In the measurement of a small antenna the antenna feed
cable forms easily a part of the radiating system. In order
to get rid of this harmful effect an opto-electronic transmit
/ receive link has been developed in-house.
