[SOLVED] 433 mhz yagi antenna uses and its design

[pugazhanthi]

i am doing project on PCB yagi antenna.What are the components used for 433 mHz to receive any channel in Tv. and another question is what are channel available in the 433 mHz?

433 MHz is the frequency used for UHF remote control devices like remote car door openers and garage door openers.

i think, master pugazhanthi, you must use the FCC table of TV channels and frequencies, then start you're design with yagi antenna..

i don't know if you can use PCB design on yagi antenna for VHF,and UHF frequencies...

maybe youcan refer to TV channel and frequency guide in youre country..

ex.
compute first for the wavelenght of the frequency you are going to design
second, wavelenght/2 = dipole overall lenght (this must be cut into 2)
3rd, dipole lenght - 45% = director lenght
4th, dipole lenght + 55% = reflector lenght
wavelenght/10 is the spacing between the elements...

good luck master...
