When you connect two metals, the result is nonlinear elements, and distortion in the signal may occur. Coaxial or coax cables are electrical cables created to carry high frequency, multi-megahertz electrical signals. They contain an inner conducting wire, usually copper, surrounded by a protective double insulating layer and then an outer plastic sheath, giving them a distinctive appearance. RF (Radio Frequency) waves are generated when an alternating current goes through a conductive material. Coax cables carry radio frequency signals. They can be used with any RF system. Are All Coax Cables the Same?
The metal shield also helps protect the signal from electromagnetic interference. Thus, coax can be placed near other electronic equipment without any issues. Per the image, the Wilson400 (and the equally powerful RG-11) has the least loss per 10ft. It’s almost twice as effective compared to the RG-6 for home installations. The only mightier cable is the pricey LG600 and even pricier Half-Inch. Your installer will typically apportion the cable into shorter lengths to cover the range of the installation while maintaining quality signal strength. When selecting a coaxial connector, you will need to know the key parameters of the cable you plan to connect. These include: All coaxial cables are rated for different applications. The rating tells you everything you need to know about where the cable can be SAFELY installed. The most common are:We seriously hate dropped calls and poor coverage, so it's our goal in life to totally eliminate spotty signal:
Signal loss happens with all types of coaxial cable. As signal travels through the cable, it loses energy. It’s inevitable. With increased cable length more signal loss occurs.Communications Multipurpose (CM) Cable: CM cable, sometimes referred to as PVC cable, is the most commonly used cable rating. It’s rated for general-purpose applications, such as connecting a computer to the wall. It’s not as fire-retardant and will release toxic fumes. They are not to be used in riser or plenum spaces. As a result, RF signals can be carried over long distances with little interference or loss. Depending on your application, the signal is then converted into images, audio, WiFi, or amplified cell reception. What are the Uses and Applications of Coaxial Cables Attach the connector to the wire by applying pressure. Use a compression tool – for example, a pair of pliers – or a more specialist crimping tool. Crimping is only a modified form of compression, so the two methods are very similar. In both cases, insert the connector which has been placed over the cable into the tool and apply firm pressure. Finally, spray liquid electrical tape to any remaining exposed areas and allow this to dry Signal gain and loss are measured in decibels (dB), which are measured exponentially. A loss of 3 dB means a weakened signal by 2x! The only way to connect a male to male or female to female is with a coax cable adapter, which also causes signal loss. Signal attenuation from an adapter will depend on the quality.
RG58 and RG174 cables are used in vehicle boosters. The difference between the two is the better low-loss quality of the RG58 with cable length up to 20 feet compared to the RG174’s 6 feet. For large vehicles, such as RVs or boats, the RG174 is preferred. Connector damage – If a connector comes loose, rusts, or breaks, the cable can't efficiently transmit information from one source to another or at all. Ohm cables tend to be better for high power handling applications. These could be commercial boosters, broadcasting TV transmitters, and ham radios. 75 Ohm cables are the popular choice for home and office applications. They're used for residential signal booster installations, cable TV boxes, internet routers, and the like. These are general rules and do not apply to all types of cable.
If there is already a connector in place, remove it. It may respond to a simple twist or you may need to make use of a tool such as a construction knife or wire strippers Both are fitted with SMA connectors. These are small, copper connectors used in modems and the like. They are relatively inexpensive, which allow for the cable’s cheaper cost. Wilson400 cables are 50-ohm, pro-grade coaxial cables designed for large installations from 7,500 to 50,000 square feet. Cable length ranges from 2 to 1000 feet, spooled. A braided mesh made from copper then helps to shield the cable from electromagnetic interference (EMI) What is the difference between 50 and 75 Ohm cables? This analogy might help. Think of signal as a drink and cables as straws. 75 Ohm cables are your typical soda straws, and 50 Ohm cables are jumbo straws.
