Raspberry Pi Compute Module 4 Antenna Kit

This Antenna Kit is certified for use with the Raspberry Pi Compute Module 4. If a different antenna is used, then separate certification will be required, and this must be arranged by the end-product design engineer.

Fitting instructions

1.Connect the U.FL connector on the cable to the U.FL-compatible connector on Compute Module 4

2.Screw the toothed washer onto the SMA (male) connector on the cable, then insert this SMA connector through a hole (e.g. 6.4 mm) in the end-product mounting panel

3.Screw the SMA connector into place with the retaining hexagonal nut and washer

4.Screw the SMA (female) connector on the antenna onto the SMA (male) connector which now protrudes through the mounting panel

5.Adjust the antenna to its final position by turning it through up to 90°, as shown in the illustration below.
