7MM5 Test (Verifying the previous 7MM Antenna tests)

Filed under: Uncategorized — derek @ 3:50 pm

This first boxplot is a boxplot of another test with the 7MM Antenna with the same orientation as before with the heights 0.1m and 0.35m. When I came into run this test I noticed the test setup had the distances 0.2m and 0.45m and this is what appears to be the heights the last test was run at. Now this may not have an effect on the data, but this could be what made Mike’s test look so much different. Because of this I just ran two tests, one with the heights we want (0.1 and 0.35) and one with the heights the setup was left at (0.2 and 0.45). The following plots are of this data.

These data and plots appear to show that the subtle height differences between the tests appear to have little effect on the results. We are still getting good separation from 0.25m from all other distances.  The following plots are of the altered height test setup

These two tests verify the results of previous 7MM Antenna tests such as 7MM1 and 7MM3 / 7MMG2
