The 1999 made-for-television movie Pirates of Silicon Valley (and the book on which it is based, Fire in the Valley: The Making of the Personal Computer) describes the role the Homebrew Computer Club played in creating the first personal computers, although the movie took the liberty of placing the meeting in Berkeley and misrepresented the ...
Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. [1] Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products.
A Yagi antenna may have a reflector on one side of the driven element, and one or more directors on the other side. If all the elements are in a plane, usually only one reflector is used, because additional ones give little improvement in gain, but sometimes additional reflectors are mounted above and below the plane of the antenna on a ...
However, a Yagi with the same number of elements as a log-periodic would have far higher gain, as all of those elements are improving the gain of a single driven element. In its use as a television antenna, it was common to combine a log-periodic design for VHF with a Yagi for UHF, with both halves being roughly equal in size.

Homebrewing kits come in many different types and from many different manufacturers. A local homebrew store may create some of their own kits by packaging materials together. Most kits come with a full set of instructions for brewing. These instructions, sometimes called recipes, may vary widely in the amount of instruction given.
A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...
A rooftop television antenna, an endfire parasitic array consisting of a combination of a Yagi and log periodic antenna Parasitic array – This is an endfire array which consist of multiple antenna elements in a line of which only one, the driven element, is connected to the transmitter or receiver, while the other elements, called parasitic ...
