We went out to our site yesterday and ran a test grid. It is so hard to walk about there. So we ran a 10 meter by 10 meter grid in the heat of the day. We were sweating but I made sure to bring plenty of water with us. In the end I came to a conclusion that we will need to run another test but this time with a very much lower diel constant to get better penetration. Tomorrow if it is not raining we will go out and run another test.
