Posting results of Single VS. Co-phase

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:

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*)

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
