    Description

    What's special about this Pi 4 Model B?
    Want to use an external antenna with the Raspberry Pi 4 Model B? These
    Raspberry Pi 4 boards are
    carefully hand-modified to add a U.FL connector and connect it up. This greatly expands the options for external antennas, and there is no additional dongle needed.
    For the greatest flexibility with your plans, these are available as the board only, with an included Molex antenna on the end of a 100mm flexible coaxial cable (Manufacturer part #206994-0100), or with a panel mount antenna with a +2dBi gain (Manufacturer part #SC0480). They are available with 2GB, 4GB, or 8GB of RAM.
    Does the external antenna provide a better WiFi signal?
    That depends on the choice of antenna. However, in my testing I've noticed an improvement over the built-in antenna when using even a mildly directional antenna, properly positioned. The largest reason to use an external antenna is if the Pi is being used in a project where the PCB antenna will be obscured (for example, inside a metal enclosure). In that case, using an antenna on the end of a short piece of coax can let you route the antenna onto the outside of the enclosure.
    What quality assurance (QA) testing is performed?
    Following the modification, every Pi is tested using a partially automated process to confirm that the new antenna connection is working properly. These are all logged by Pi serial number along with the test statistics to determine a PASS/FAIL state. A QA testing certificate is provided with every individual Pi following a successful PASS. There may be some cosmetic melting of the GPIO header plastic due to its close proximity with the modification area. However, this doesn't impact the functionality or performance of the device.
