Overview

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

Fitting instructions

1 Connect the MHF1 connector on the cable to the MHF connector on the

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 nal position by turning it through up to 90°, as

shown in the illustration below
