13. Antenna Recommendation

13.1 Antenna Recommendation

Antennas are an important role in the communication process, and often inferior antennas will have a great impact on the
communication system. Therefore, our company recommends some antennas as supporting our company's wireless modules with
excellent performance and reasonable prices.
