The 2.4Ghz directional antenna is a high gain, excellent choice to use RF Explorer analyzer to scan in a specific direction. As opposed to omnidirectional antennas such as dipole type, this patch antenna has an 8dBi gain in the front face. It includes a true SMA connector (not RP-SMA as most in the market) and therefore fits perfectly in all RF Explorer models.
This antenna is suggested for high sensitivity detection of RF sources with RF Explorer Spectrum Analyzer, including distant transmitters, focus and orientate antennas or find nearby hidden bug devices. It is also perfect to find your lost drone or RC plane as long as still transmit valid signal.
Alternatively, it can be used in the RF Explorer Signal Generator to produce a quality long distant RF source to determine path loss and adjust antenna orientation in a RF link.
