      Fractal Antenna

      A fractal antenna is a diamond-shaped antenna that maximizes the total amount of material within a given amount of space that transmits or receives electromagnetic waves. Fractal antennas do this by making each section of the antenna its own separate dipole. Because of this design, fractal antennas operate at many different frequencies and wavebands, allowing

    • Modulation


      Modulation is the process of varying some characteristic of a periodic wave with external signals. Modulation is utilized to send an information bearing signal over long distances. Radio communication superimposes this information bearing signal onto a carrier signal. These high frequency carrier signals can be transmitted over the air easily and are capable of traveling

    • What is an Isolation Transformer?

      What is an Isolation Transformer?

      An isolation transformer is made of two copper coils that are wound around each other and are each supplied by their own power source. While the term “isolation transformer” technically refers to any transformer, it is specifically a transformer that isolates a circuit from an alternating current. An isolation transformer does this by separating two

    • Ham Radio Software

      Ham Radio Software

      Ham Radio Software, also known as Amateur Radio Software, refers to computer programs designed exclusively for ham radio equipment. Once thought to be a means of communication between radio enthusiasts, ham radio now coexists with software including data and contest loggers, log books, Morse code tutors, and antenna design aids. In the 21st century there

    • Siemens (Unit of Electrical Conductance)

      Siemens (Unit of Electrical Conductance)

      The siemens is the standard unit of electrical conductance. It is the inverse of resistance and is equal to one divided by resistance, or current divided by voltage. One siemens is equal to one ampere per volt. History of the Siemens The siemens was defined at an international conference in 1881, and is named after

    • F Connector

      F Connector

      The F connector is a particular type of radio frequency connector that was developed in the early 1950’s. Eric Winston is usually credited with the creation of the F connector, while developing cable television as an alternative to the broadcast television options of the day. What does the F Connector do? The F connector provides

    • GPS (Global Positioning System)

      GPS (Global Positioning System)

      GPS stands for Global Positioning System.  It refers to a system of satellites that constantly transmit a signal, and a GPS terminal that picks up those signals and calculates its position on Earth by measuring the distance between itself and two or more GPS satellites (by measuring the time it takes to receive the signals).

    • Laser Diode

      Laser Diode

      A laser diode is a small device that is similar in construction and appearance to a light emitting diode (LED). The main difference is that a laser diode produces coherent laser light while an LED produces incoherent light. Ever since they were first invented in 1962, millions of laser diodes have been used in a

    • LNB Tester

      LNB Tester

      Before you ask what an LNB tester is, you should know what an LNB is. An LNB is the receiving end of a satellite dish. LNB stands for low noise blocker; it is a device that essentially does what it says. It blocks low noise (frequencies) in order to receive higher frequencies in which satellite

    • BGA (Ball Grid Array)

      BGA (Ball Grid Array)

      BGA (Ball Grid Array) is one type of packaging for surface-mounted integrated electronic circuits (integrated circuits whose components are actually ‘mounted’ or affixed on the surface of the printed circuit semiconductor board). A BGA package simply looks like a thin wafer of semi-conducting material that has circuit components on only one face. The Ball Grid
