Waveguides are used at higher frequencies where their loss is lower than coaxial cable. Coaxial cable is used at lower frequencies where waveguides are too large and heavy. Lastly Coaxial cable is also used at higher frequencies where some flexibility is required.

What is the bending radius of a cable?

Typically, wires have a bend radius of 10 times the diameter of the wire. Measuring the inside. This is basically to prevent injury or changes in impedance at the bend. Also note that the tighter the bend can damage the insulation in coaxial or triaxial cables and cause lower dielectric strength between layers. Best to install cables where ripples don't form on the surface and moderate force is recommended. MIL-W-5088 has more information.


What is the frequency in hertz of gma ch 7?

The frequency of Channel 7 on GMA will depend on your location and the broadcasting station. You can check your local TV guide or contact your cable/satellite provider for specific frequency information.


What is the function of the concave pole pieces and the coaxial soft-iron cylinder in the moving coil galvanometer?

The concave pole pieces focus the magnetic field onto the coil, enhancing sensitivity. The soft-iron cylinder helps to guide the magnetic field lines, allowing for efficient interaction with the coil. Both components work together to improve the performance and accuracy of the moving-coil galvanometer.


Guide wavelength and their relationship with free space wavelength?

One specification listed for waveguide or coax cable is its "velocity factor". This is the fraction that represents the speed of E&M within the medium compared with the speed of light in free space. It's always less than 1. For some media, as little as 65%. Since wavelength is (speed)/(frequency), lower speed directly implies shorter wavelength in the guide. This is important when the transmission line is not terminated in its characteristic impedance, and its 'electrical length' ... length measured in wavelengths ... directly influences the load characteristics at the source.

What type of cable is an cable modem used for?

You should use an RG-6 cable RG-6 A type of coaxial cable with an impedance of 75 ohms and that contains an 18 AWG core conductor. RG-6 is used for television, satellite, and broadband cable connections. Source = Network+ Guide to Networks (Fifth Edition) by Tamara Dean


Why is broadband cable less commonly used by businesses than DSL ot T-carrier services?

Because most office buildings are not wired with coaxial cable. Pg. 323 of Network+ Guide to Networks


Why is a broadband cable less commonly used by businesses than DSL or T carrier services?

Broadband cable is less often used in businesses because most office buildings do not contain a coaxial cable infrastructure. Network+ Guide to Networks pg 323 fifth edition.


What is the purpose of the front derailleur cable guide on a bicycle?

The purpose of the front derailleur cable guide on a bicycle is to route and guide the cable that controls the movement of the front derailleur, which is responsible for shifting the chain between the chainrings on the bike's crankset.


Is coaxial cable able to keep out interferance and carry long distances?

Coaxial cable is designed to shield the communications medium from EMI and maintain the integrity of wire transmissions. There are specific distances that various types of coaxial cable can travel without repeaters or bridge filters. The most typical distance for ethernet is about 100meters. High-Speed (DSL) cables can go up to a mile before performance suffers. There are several types of cable in use to support various transmissions. The older STP, Thinnet/RG-58 cable used for ethernet has been replaced by Category-5 cable. Radio feed-lines use RJ-58, LMR-400 or even hard-line "wave guide" between transmitter and radiator (antenna). Cable Television is really the only mass-broadcast medium that still uses cable. It's important to remember that the coaxial connections are as critical as the coax quality it self. An exposed ground-shield on one end of a cable can both radiate unauthorized emissions, as well as be subject to interference from external EMF sources.

Where is a cable guide for local tv listings?

Every area has different channels and thus different listings. Check your local Cable Television website online or call them to have them send you a channel guide. If you are asking about your electronic program guide or EPG for analog cable TV, it is usually located near the lower number channels. If you have a digital cable TV box, you should have a guide button on your cable remote.
