HOW YOU CAN USE Dirt Cheap Bi-Directional Antenna to Wirelessly Extend Your LAN!!!
A biquad is a fairly powerful antenna which is relatively easy to construct, with impressive performance for their size. A link greater than 5 miles can be made with a pair of these as a stand-alone antenna and a Prism2 100mW card, provided you keep coax short, and your line-of-sight is clear.
The fairly wide beamwidth of a biquad makes it ideal for stumbling, and also makes p2p links easier to setup, as the alignment isn’t as critical. The 3dB beamwidth of a biquad is typically about 40-50 degrees.
They can be used as a feed for a dish, or can be used stand-alone.
