Were these antennae used as the transmitting or receiving antennae?
If transmitting antennae then what was the receiving antenna and
receiving equiptment. Second unknown is the path loss between the
transmiting antenna and the receiving antenna. Third item what was the
gain(dBi) of the receiving antenna. Without the above data, the above
results meaningless.


Who's talking dbi ? I'm not. The reference was the RS deluxe mag
mount. Referenced at 0db

As I explained. The order of best to worst is accurate. Calibrating
the results into db is as explained below. Meaningless? I don't think
so.

This test was done with an in sight very low power remote transmitter
located about 200 yards away. A regular CB was used with low
readings on the S-meter to give me a relative field strength. The
exact S numbers were noted. Then next step was to calibrate the
readings.

The db calculation were computed after taking the same CB and exciting
it with a variable power transmitter to see how the noted S-meter
readings related to power output of the variable transmitter.
