The WokFi antenna is considered simpler and cheaper than other home-built antenna projects (such as the popular cantenna), but is a very effective method to boost the Wi-Fi connection quality, audit access point coverage, and even quickly establish WLAN viability – perhaps if a more professional setup is eventually intended.
Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are specialized parasites of other crustaceans, with reduced bodies. Barnacles have existed since at least the mid-Carboniferous, some 325 million years ago. In folklore, barnacle geese were once held to emerge fully formed from goose ...
The resulting setup is a low-cost high-quality high-gain antenna. [6] Such setups are widely used in wireless community networks for long-distance Wi-Fi links. Cantennas may be used with other RF devices such as wireless security cameras. [7]

Chthamalus antennatus, the six-plated barnacle is a species of intertidal barnacle found in eastern and southern Australia. Growing from two centimetres wide and one centimetre high. The barnacle is found on the coast, usually on rocks at or above the high tide level or just below the splash zone. Feeding occurs only at unusually high tides. [1 ...
Megabalanus tintinnabulum is a species of large barnacle in the family Balanidae. It is the type species of the genus. The specific name comes from the Latin tintinnabulum meaning a handbell and probably refers to the fact that small groups of barnacles resemble clusters of miniature bells.
Megabalanus californicus is a large acorn barnacle with a diameter of up to 30 mm (1.2 in). The steep-sided shell is formed of six plates finely striped vertically with reddish-purple and white. There are relatively wide, reddish radii between the plates where they fuse.
Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
