    • Linear LNB

      Linear LNB

      LNB stands for low noise blocker and it is essentially an amplifier on the end of your small satellite TV dish or communications dish. The “Linear” portion of Linear LNB stands for the characteristics of the radio waves that are transmitted via the satellite in space to your dish (LNB). Two Types of Polarization Circular

    • Shunt

      Shunt

      An electrical shunt is a component used to transfer currents away from parts of a circuit. Components used as shunts include the resistor, capacitor, diode, and gas discharge tube. The main uses for electrical shunts are to reduce current load in meters, filter out high frequencies, and protect circuits from surges. The term shunt is

    • How to Use a Multimeter

      How to Use a Multimeter

      A multimeter is used to take measurements of electrical properties for a circuit such as the voltage, current, or resistance. A modern multimeter combines the abilities of legacy voltmeters, ohmmeters, and ammeters. Some of the uses of a multimeter include electrical testing on electrical power sources, motors, and other electrical circuits or components. They are

    • Rectifier

      Rectifier

      A rectifier changes alternating current into direct current. This process is called rectification. The three main types of rectifier are the half-wave, full-wave, and bridge. A rectifier is the opposite of an inverter, which changes direct current into alternating current. Half-Wave Rectifier The simplest type is the half-wave rectifier, which can be made with just

    • Frequency Changer

      Frequency Changer

      A frequency changer makes it possible to change electricity moving at one frequency to another frequency. However, in order to fully understand what a frequency changer does, it is helpful to understand the frequency of electricity. The Frequency of Electricity Electricity doesn't move at one specific speed. In fact, it can move at many speeds.

    • 8PSK

      8PSK

      8PSK (8 Phase Shift Keying) is a phase modulation algorithm. Phase modulation is a version of frequency modulation where the phase of the carrier wave is modulated to encode bits of digital information in each phase change. The “PSK” in 8PSK refers to the use of Phased Shift Keying. Phased Shift Keying is a form

    • Military Alphabet

      Military Alphabet

      The military alphabet, or more properly the phonetic alphabet, exists in innumerable variants. If any military alphabet can be viewed as the most correct, it is the current NATO standard military alphabet. However, even with the NATO standard military alphabet, various member nations use numerous spelling variations. This version of the military alphabet is also

    • What is a Loop Antenna?

      What is a Loop Antenna?

      A loop antenna is one that is designed to receive radio signals more efficiently than other antennas. Loop antennas are considered more efficient than others because they are mobile, work with a wide range of frequencies, and use less electricity. A loop antenna’s performance is entirely dependent on its construction and placement, although other factors

    • Breadboard

      Breadboard

      A breadboard is a thin rectangular piece of insulating material used to hold electronic components when making circuit prototypes. They have many rows and columns of conductive points for inserting component terminals and jumper wires. The original breadboards were just wooden boards, presumably used to cut bread on, but the modern versions have plastic cases

    • Linear Amplifier

      Linear Amplifier

      Linear amplifiers are electronic circuits that have an output that is proportional to the input of the device while providing additional power to the load. A linear amplifier is normally a variant of a radio-frequency (RF) power amplifier and is used frequently in amateur radio and in laboratory and commercial audio equipment with an output
