Suggested Module Placement Region
High-Flying suggest HF-LPB100 module better locate in following region at customer board, which to
reduce the effect to antenna and wireless signal, and better consult High-Flying technical people when
you structure your module placement and PCB layout.
1.2.5. External Antenna
HF-LPB100 module supports internal antenna and external antenna option for user dedicated
application.
If user select external antenna, HF-LPB100 modules must be connected to the 2.4G antenna
according to IEEE 802.11b/g/n standards.
The antenna parameters required as follows:
