Once the sensor orientation is decided, locate four points are located approximately(usually) 50m from the site center for Ex(close to N-S) and Ey(close to E-W) telluric dipoles.
The electrodes should be placed in 15-20cm deep holes for stable and good contact. It is recommended to use bentonite at the bottom of the hole.

Next, locations for are selected magnetic sensors, apart from the telluric lines to minimize interference between sensors. And also away from trees(watch roots too) to avoid noise due to ground vibration by wind. Bury the sensor coils in the ground to minimize noise from movement and temperature variation. Hx and Hy should be placed horizontally and Hz vertically.
