BBL P1S Antenna Problems

The antenna pattern direction is horizontal

The radiation pattern of WiFi radio waves spreads perpendicularly to the antenna The Z-axis is the pattern on the PCB

If the router or AP is located on the side of the P1S printer, wireless performance degrades

It improves wireless communication with routers in a horizontal position by making the printer's antenna vertical
