These external antennas are the perfect way to extend the wireless range of your Particle-powered Wi-Fi project.
The ultra portable Flex Antenna is particularly useful when space is at a premium, but you want a little more range than a chip or trace antenna can provide. It requires no additional connector — it attaches directly to the u.FL connector already on your Core u.FL or Photon.
The Duck Antenna is especially great for projects that need a metallic enclosure, which often block Wi-Fi transmission. The antenna includes an interface cable for RP-SMA to u.FL. The Duck Antenna can be used with the Photon as well as Cores with u.FL connectors.
