Note:
⚫ The VSWR of the antenna should be less than 1.5.
⚫ In order to achieve the best reading range, the coaxial cable between the
reader and the antenna must have a certain length. For all antennas of our
company (such as DA3807), the optimal length of coaxial cable is 2~2.5
meters.
⚫ To prevent external coupling noise, the antenna cable can be installed with an
attached EMC ferrite ring core of 28mm x 20mm. The antenna cable must be
wrapped around the ring core for 3 to 5 turns. The distance between the ring
core and the reader connection must not be more than 10 cm.
