Tucked inside the exterior casing, the traditional Yagi elements -- metal antenna dipole, directors, reflectors, low noise and anti-interference amplifiers -- are re-engineered to achieve a similar gain level and receive uncompressed high definition digital signals.
In particular, when the resonant mode is excited, a cyclic plasma movement of free electrons is induced in the metal antenna. The electrons freely flow along the antenna, generating alternating current at the same frequency as the resonance flowing toward the antenna feed point.
"Misinformation about the possibility to detect weapons and explosives by using one and the same device is propaganda perpetuated by traders who have drowned the Lebanese market with a vast number of devices that are connected to a metal antenna," said Sami Zod from Zod Security, in a memo about the devices.
Alphie needed emergency surgery when the metal antenna became lodged in his oesophagus and stomach.

Earlier this month, Ethertronics announced a new Prestta(TM) penta-band stamped metal antenna ideal for M2M-oriented products.
If a metal antenna is constructed whose surface is one of this class, its performance would he the same at all wavelengths except for rotation of the coordinate system.
