I had a radio link over 600m 2 build these antennas in use. It worked. However, after I had massive problems with disconnects, I have the two antennas replaced by a TL-ANT2414B and a TL-ANT2424B from TP-Link.
During the Yagis never more than 6Mbit / s were reached on the connection is working now with min. 50Mbi / s or more.
The specified 16dBi are a fantasy value in any case.
