## Wi-Fi antenna
|
|
|
|
|

The PiKVM V4 has a robust metal case that protects your device from physical damage and electromagnetic interference.
|
|
|
|
|
This also means that an external antenna must be used for Wi-Fi.
|
|
|
|
|
We recommend the [official Antenna Kit](https://www.raspberrypi.com/products/compute-module-4-antenna-kit)
|
|
|
|
|
for Raspberry Pi.
|
|
|
|
|
|
|
|
|
|
To install the antenna, fix it in the round hole in the back side of the PiKVM,
|
|
|
|
|
and connect the wire to the connector on the Compute Module 4,
|
|
|
|
|
as described in the [instructions](https://datasheets.raspberrypi.com/cm4/cm4-antenna-kit-product-brief.pdf).
|
|
|
|
|
|
|
|
|
|
Next, to activate the antenna, add line `dtparam=ant2` to the `/boot/config.txt` file on PiKVM.
