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.
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.
A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; [1] these elements are most often metal rods (or discs) acting as half-wave dipoles. [2]
[4] [19] All homebrew games are region free, as both systems do no enforce regional locking, but some titles do not work correctly on PAL consoles. [20] There have been conversions from Atari ST to Jaguar, as the two share the same hardware. While some of these fan works are free to download, others have been sold online.

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.
The programmer must prepare each line of video output as it is being sent to the television. The only sprite capabilities are one-dimensional 1-bit and 8-bit patterns; creating a two-dimensional object requires changing the pattern between each line of video. [1] Games are often developed using Atari 2600 emulators such as Stella and Z26. [24]
A typical AM broadcast radio loop antenna wound on ferrite may have a cross sectional area of only 1 cm 2 (0.16 sq in) at a frequency at which an ideal (lossless) antenna would have an effective area some hundred million times larger. Even accounting for the resistive losses in a ferrite rod antenna, its effective receiving area may exceed the ...
