My other thread has the results of the test and the method I used to get there. My results as I listed them were a little confusing so I made a chart to make it a little easier to view. I am also including a diagram giving examples of the truck's orientation for each test.
Results:
Orientation diagram:
Transmitt on the co-phase set consitantly out-performed the single antenna. One test showed a whole 3 S units gain over the single. Less difference was shown on receive but the co-phase had a slight edge over the single. I will test more locations someday to futher the testing. So many variables are out there, I'd need quite a few more tests to be totally conclusive. But it looks like, so far, the myth about co-phasing being useless and negative is false (*for this location of mounting the antennas*)
