Coaxial cable is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, and usually surrounded by a final insulating layer.
waveguide may refer to any linear structure that conveys electromagnetic waves between its endpoints.
A waveguide, is a hollow rectangular tube, designed to channel microwaves from the Magnetron to the outside world. Rather than use a wire, this is found to be the best way to transfer microwaves at 3 cm to 10cm wavelength. (Some 10cm systems use large coax instead) They are normally found on radar systems, to transfer the signal to and from the rotating scanner to the transceiver unit. Modern radars keep the length of the waveguide to a minimum, by housing the transceiver in the motor unit of the scanner, instead of a separate room.
Horn antenna are typically fed by a section of a waveguide, the waveguide itself is often fed with a short dipole.

It used to reduce the signal strength
No, not all coaxial cables are suitable for internet connection. It is recommended to use a high-quality coaxial cable specifically designed for internet use to ensure optimal performance and reliability.
Rectangular Waveguide - TE10; (TM11 in case of TM waves) Circular Waveguide - TE11;
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.
Circular waveguides are advantageous when working with high-frequency electromagnetic waves, such as in microwave and millimeter-wave applications. They are more efficient in guiding and transmitting these high-frequency signals due to lower losses and higher power-handling capabilities compared to other transmission mediums like coaxial cables. Additionally, circular waveguides are often used in radar systems and satellite communication due to their ability to pass through various bends and curves with minimal signal loss.
no.
Use T Connector
Because microwave circuits in waveguide use hollow waveguide sections with flanges to bolt them together.
A coaxial cable has great uses in television antenna connections. TV satellite connections also use coaxial cables to connect decoders to the TV set.
Thinnet coaxial cable uses a BNC twist connector.
