There are 3 types of polarization that can be used .

1)Vertical

2)Horizontal

3)Circular

Power amplifires are used to raise the power delieverd by the machine which is only 30w . and we have to raise it to 10kw or higher . power amplifires comes in the package of to and one stands for standby mode .

Transformer are used for impedence matching in power amplifires . there is a copper pipe from which entire power is carried to the transmitter ,. Which is made such that the inner conducting material do not get affected by outer atmospheric conditions.

Intermediate power amplifires are used to feed power amplifires enough supply to drive power amplifires.

VU metres are used to massure the noise level and the power delievered by microfone .

Power combiners are used to add the power and the necessary condition to add to power signal is that their magnitude and phase must be in sync .

The heat sync must be that element which can hold the heat . and by blowing air it will radiate the heat in air .
