How to make the antenna for A-434 (434 MHz) Transmitter and Reciever ? The required range is within 10metres. Please be elaborate as this question comes from an amateur hobbyist.
the antenna size is based on wavelength and
wavelength = c / frequency
where c = 3×1010 cm/s
so just put ur frequency in above equation. you will get wavelength in cm. then antennal length can be wavelength/2 or wavelenght/4.
