12.1 Antenna  recommendation 

The antenna plays an important  role in the communication  process. The inferior  antenna often has a great impact  on 

the communication  system. Therefore,  we  recommend  our antennas, which  have excellent  performance  and reasonable 
price, to support our wireless modules.
