Broadband, High-Gain Directional C-Band Antenna
The SL-520A-501 is a broadband, High Gain Antenna, providing continuous communications coverage across the spectrum of 4.4 GHz to 6.0 GHz and beyond.
Its primary use is to enhance Wi-Fi network signals in 802.11a and 802.11n modes in the Americas, and in the US U-NII bands (5.150-5.350, 5.470-5.725 and 5.725-5.825 GHz). In Europe the SL-520A-501 will support 802.11h ETSI HiperLAN/1 (5.150-5.350 GHz) and HiperLAN/2 (5.470-5.725 GHz) applications simultaneously. . . and, in Asia, the very same antenna will support High Speed Wireless Access applications at 5.150-5.250 GHz.
The broadband nature of this Directional Antenna allows concurrent operation on all of the above services, in addition to doubling up as a Directional Antenna in C-Band Telemetry and Video applications. For example, it can be used as a portable, high gain (+9 dBil), search C-Band Antenna, to enhance the downlink video feeds (as a first person view or fpv antenna) of remote control (RC) planes and UAVs (drones), boats, cars and robots; or to connect wireless security equipment, such as cameras. It can also be used as a point to point 5 GHz Antenna for short to medium ranges.
