                        Common Problems and Attentions:
                        1. The antenna is a circular polarization antenna. Please kindly adjust the angle to get the best reading performance in practical applications.
                        2. The antenna can be used at the outdoor environments, but it’s not good to use it in an acid/alkali environment.
