The most common aerial was invented during the Second World War (193- 45) by a Japanese scientist called Yagi. This is why they are called Yagi arrays. It works by having a minimum of three elements the centre active lement is a sub haronic of the resonant frequency, the futhest away fom the source is the reflector (10% longer) and the nearest is the director (10% shorter). Most aerials have many more directors and a single reflector. This prevents interfering signals entering the system from the rear.
