This is a long range transmitter.This circuit can send signals up to 2km.So that you have to use 1m copper

Television (TV) is the view (display) the image of a place / location of the remote. The image seen on the TV screen is the result of a reproduction of the object by the TV camera lens and separated based on the basic color, then, the signal is transmitted through the air or cable and then received by a search plane, TV system. In the plane TV. TV in the plane, a red signal is sent to the TV ketabung layer dephosphorize red and so on. Results dephosphorize circulation is a picture we can see.
In addition to emit a signal transmitter also send the image signal and sound to the speakers produce sound. Basically consist of several television series of the blocks is very important to support these processes bekerjanya television. Series is the tuner, audio manager, image manager, syncronisasi, image control and a vertical and horizontal image of a high voltage, and share resources. Pictures can be viewed on the diagram page terakhir.Rangkaian tuner (consisting of: local Osc, Mixer and RF AMP) that serves to manage the signal received by the antenna of the television transmitter.
Rankaian sound management (IF AMP Sound, Sound Det, or AMP Audio Power Amplifier and speaker) that functions to ensure the information signal from the sound signal carrier frequency so that the middle voice into audio signals and can be heard by manusia.Pengelola image (Video IF, Matrix, video amplifier), which serves to manage the image signal so that it can activate the picture tube and can display images on the CRT screen.

Radio waves are generated by electrons accelerating in the antenna.
Consider a transmitter perpendicular to the ground. The electrons in the antenna, when a signal is applied, are changing their velocities continuously (i.e. moving up and down very quickly) in response to the applied signal.
For a station that broadcasts at a wavelength of 1500m, the antenna needs to be 750m long. This is because there is a ‘virtual antenna’ caused by the aerial being earthed in the ground:

An analog transmitter is a field-mounted device that senses a physical parameter such as pressure or temperature and generates a current proportional to the measured variable in the standard range, 4 to 20 mA. Providing the output as a current in a twisted-pair loop has many advantages: the measurement signal is insensitive to noise and is not affected by changes in loop resistance; transmitters meeting the standard are interchangeable; and the power required to energize the transmitter circuits can be derived from a remotely supplied loop voltage. Figure 1 shows a conventional transmitter circuit, consisting of a power supply, a current-manipulating transmitter, and a receiving controller.
