Advantages: No cables needed multiple channels available, wide bandwidth.
Disadvantages: Line-of-sight will be disrupted if any obstacles, such as new buildings, are in the way. Signal absorption by the atmosphere. Microwaves suffer from attenuation due to atmospheric conditions. Towers are expensive to build
1. Provides a high data rate.
2. cost of purchsing towers for transmission is pretty low.
3. small antennas are required.

advantages of micro wave transmission
Microwaves are electromagnetic radiation. They are electromagnetic waves, and they are transmitted like light or radio waves, both of which are forms of electromagnetic radiation. The radiation leaves the microwave source in waves, and this radiation will travel effortlessly through a vacuum, and with a bit of loss through air.
pg clamp is known for parallel groove clamp,especially used in transmission line to hold transmission conductors in parallel.
Transmission and distribution voltages are normally expressed in terms of line voltages, so the answer is that the figure you quote is a line voltage. Incidentally, do you really mean 230 megavolts for a transmission voltage?? And the symbol of kilovolt is 'kV', not 'kv'.

at microwave frequency why should the transmission line may considered to be made of unit length?

The main limitations to Microwave transmission is the fact that it needs line of sight and that it can be subject to interference such as planes passing over, or rain
what are the Microwave Diathermy advantages and disadvantages
Microwave transmission can be achieved via terrestrial or satellite systems
it is the transmission of microwaves. One person throws a microwave to another person and so on.
They can be interfered by other transmission signals

Due to corona effect virtually conductor size is increase and therefor resistance in transmission line is decreases.so I2R losses will decreases...
microwaves are line-of-sight. the higher you are the further the horizon is.
Impedance Inversion in Microwave circuits can be obtained by utilizing the Short Circuit or Open Circuit Transmission line of proper length.
