Servus und guten Abend, Community,
da ich momentan mal wieder an dem Thema arbeite, hab ich hier mal ein paar Artikel zusammengestellt - rund um Themen /& Dinge wie
- Raspberry Pi 3B+ mit externer WLAN Antenne
- Antennen für 2.4 und 5GHz WLAN mit 12dBi
- Messverfahren mit Wavemon, -kismet, Wifi Analyzer, Network manager command line interface nmcli oder mit linssid
hier gehts los - wie gesagt mit einer schlichten Sammlung von Threads & Artikeln

....einschränkend: Be aware that this will invalidate the RPi WiFi type approval, is therefore illegal in many jurisdictions, and could result in a prosecution.
In this video, we go over the detailed, step-by-step instructions for adding a U.FL connector to the Raspberry Pi 4 to support external antennas. We then also compare a few different ways of disconnecting the internal antenna to see which one gives the best result.
by the way - in diesem Zusammenhang immer auch interessant - LORAN discussions for the esp 32

wavemon https://github.com/uoaerg/wavemon
wavemon is an ncurses-based monitoring application for wireless network devices on Linux.
wavemon is a wireless device monitoring application that allows you to watch signal and noise levels, packet statistics, device configuration and network parameters of your wireless network hardware. It should work (though with varying features) with all devices supported by the Linux kernel.
Wifi analyzer Android-Application für WAP-Management, Wifi-signal etc.
Kismet is a 802.11b wireless network sniffer. It is capable of sniffing using almost any supported wireless card using the Airo, HostAP, Wlan-NG, and Orinoco (with a kernel patch) drivers. Can make use of sox and festival to play audio alarms for network events and speak out network summary on discovery. Optionally works with gpsd to map scanning.
