14 Antenna Guide

14.1 Antenna Recommendation

Antennas play 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 antennas with excellent performance
and reasonable price to match our wireless modules.
