Two holes for M5 screws are provided for mounting the antenna. The maximum screw head
diameter is 9 mm. The antenna is suitable for mounting on metallic and non-metallic
surfaces.
Note
Achieving optimum wave propagation
To achieve optimum wave propagation, the antenna should not be surrounded by
conducting objects. The area between antenna and transponder should also allow wave
propagation without interference.
Note
Antenna gain depends on the mounting surface
Note that the antenna gain depends on the material of the mounting surface. If the antenna
is mounted on a metallic surface, the antenna gain is -5 dBi. If the antenna is mounted on a
non-metallic surface, the antenna gain is -10 dBi.
Note
