This is a 5-pack of whip antennas from TE Connectivity/Linx Technologies, model ANT-ELE-S01-005. They're designed for the 860-960MHz frequency range, which is common for RFID, cellular, or other wireless data applications. The key feature is the magnetic base mount, which lets you easily and temporarily stick the antenna to a metal surface for testing or semi-permanent installation. A super convenient option for prototyping, field deployments, or situations where drilling holes isn't wanted. The pack of five is great for having spares or setting up multiple units.
