Wireless Yagi is ideally suited for directional and multipoint 2.4 MHz band applications. Wi-Fi Yagi antenna is the most popular type of directional antenna in use today. The 15dBi 2.4Ghz Outdoor Yagi Antenna offers 25 deg Vertical and 30 deg Horizontal Beam width. It is only 25" long. This Wi-Fi Antenna comes with an N-Female pigtail connector. N-Female is an industry standard connector. It has threads on the outside and a center socket. The Yagi antenna operates without the need for a grounding in most cases. However, you can ground antenna via the outer conductor of the connector and the cable, or through the mounting hardware. We do, however, recommend you install a lightning surge protector between the Yagi and a device to prevent a lightning strike to the antenna from damaging your device and equipment. Wireless Yagi Antenna TP512 in most cases can not be attached directly to the device (Wi-Fi router, signal booster, etc.) without some type of cable converter/adapter This Antenna has N-Female cable/connector so it will need the cable/converter from N-Female type to [your device connector type], usually to some pigtail coax RP-SMA cable connector. Also, you can put amp of some kind or signal booster between device and antenna. The Yagi antenna is used to direct the Wi-Fi beam. It will increase the signal/reception in the direction it is pointing. Electrical Data: Frequency: 2400-2483 MHz Gain: 15 dBi VSWR: 16 dB Max Input Power: 100 W Lightning Protection: DC Ground Mechanical Data: Connector: N Female Dimensions: 24.81in Weight: 0.93 lb. Cable Length: 9.45in Reflector Material: Aluminum Alloy Antenna Material: Mast Size: Ø40-Ø50mm Rated Wind Velocity: 210km/h Operating temperature: -40~+65C.

In the game of anonymity-versus-surveillance online, the discovery of the user’s IP address usually means game over. But if Ben Caudill has his way, a network snoop who successfully hunts a user through layers of proxy connections to a final IP address would be met with a dead end—while the anonymous user remains safe at home more than a mile away.

Conditions over Field Day weekend turned out to be not bad at all. The expected geomagnetic upset never happened. On June 25-26, the Thursday and Friday before Field Day, the predicted planetary A index for the June 27-28 was 45 and 60, really bad conditions. The actual planetary A index on those dates was 9 and 13, and the mid-latitude A index was 8 and 12, nice moderate numbers.
