1、RF optional standards：United States 902-928MHz; The best working frequency of this antenna is 923MHz.
When it is used with our AS3992 reader, set the working frequency of reader be USA standard (902.75MHz~927.25MHz), which is the best for working. The distance of scanning a tag can reach 1m. This kit can read up to 30 labels at the same time when the labels are close to the antenna.
2、Optional connecters: normal ones are N series, SMA series, TNC series and etc.
3、Optional appearances. Gains are different from high to low according to the size of the antenna. We have several antennas. You may choose as you need.
