We were using this antenna 900-2600 at an out of town laboratory for RF measurements. The engineer at the laboratory told me that the antenna had a gain of 3dB, but if I calculate gain from the antenna factors in the datasheet I get about 6dBi.

I guess the plot on page 2 is return loss, but what is shown on page 3?

E-mailed the designer as Tony Stewart suggested. Apparently the gain is between 4.5 and 6dBi. He also said, that he did not know what page 3 was, but it was probably added to the datasheet by mistage.
