      DVB-RCS

      DVB-RCS stands for Digital Video Broadcast – Return Channel Satellite. DVB-RCS is part of the DVB standards for satellite communication, DVB-S and DVB-S2. The purpose of DVB-RCS is to provide a return channel to enable Internet and other data services over satellite. ViaSat’s LinkStar system is one of the VSAT satellite broadband implementations which support

    • What is Intersymbol Interference?

      What is Intersymbol Interference?

      Intersymbol interference is a signal distortion in telecommunication. One or more symbols can interfere with other symbols causing noise or a less reliable signal. The main causes of intersymbol interference are multipath propagation or non-linear frequency in channels. This has the effect of a blur or mixture of symbols, which can reduce signal clarity. If

      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

    • GPS Jammer

      GPS Jammer

      GPS stands for Global Positioning System. It is used by individuals, commercial entities and the military for navigational purposes. GPS uses 24 satellites that orbit the earth and send radio signals. The GPS satellites work with a GPS receiver which today can be found in individual handheld units, car navigational systems, boat navigational systems, highly

    • L band

      L band

      L band is a fequency range between 390MHz and 1.55GHz which is used for satellite communications and for terrestrial communications between satellite equipment. The high frequencies utilized by C band, Ku band, and Ka band would suffer from high signal loss when transported over a copper coax cable such as an Intra-Facility Link. An LNB

    • BNC Connector

      BNC Connector

      More properly known as the Bayonet Neill-Concelman connector, the BNC connector is one of several radio frequency connectors on the market today. The name of the connector is derived from a combination of two things: 1) the connecting technology employed; and 2) the names of the two inventors of the device. Paul Neill of Bell

    • Mobile Satellite Service

      Mobile Satellite Service

      Mobile Satellite Service (MSS) is a type of mobile telephone service that depends on portable terrestrial satellites rather than fixed terrestrial satellites that are also known as cell phone towers. Portable terrestrial satellites are similar to cell phone towers, but can be mounted on moving vehicles such as cars, ships, and airplanes, and individual users

    • 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

    • Internet Repeater

      Internet Repeater

      An Internet repeater is a device that allows amateur radio operators to communicate with each other over the Internet, much like how VoIP software allows telephone operators to communicate with each other over the Internet. Internet repeaters should not be confused with wireless repeaters, which allow users to extend the range of a wireless network.

    • What is a Balun?

      What is a Balun?

      A balun is an electrical transformer that is used to convert electrical signals to and from balanced and unbalanced signals. They are normally used to connect lines that have different levels of impedance and are commonly used in the home for connecting HD and traditional antennas. Baluns are also used throughout industry, although it is
