This project is presented PR Board wireless singnals to Coaxial cable, for use in the press releases In the Faculty of Engineering Thonburi University by sending wireless signal for the convenience of the use.
The design use the computer with video card VGA in the picture output to send a signal to the video transmitter the UHF by using a TV LCD 32 inch as a receiver.The display divided into 4 screens for use in the press releases in section 4 the public relations
From the experiments wireless video transmission the UHF which has a frequency in the range 430 – 520 MHz will be shown in the frequency range.495 MHz will can send the image clarity in 10 meters. But if out of the distance of 10 meters there will be a flicker images are not able to receive images. Due to a signal UHF as the wave public signal Therefore, there is an external signal noise is quite easy It is not able to send the image to a distance
