Make A Simple Halfwave Dipole Antenna for TV

In this article I will show you how to make simple a halfwave dipole antenna for home TV reception using 2 radiators , consist of two 1/4L coaxial cable and feed point .
The video for how to make this simple antenna also you can watch on my youtube channel.

Digital TV frequency band is 470-800 MHz , depends on your country and location, you can adjust with your own frequency used. So, based on that frequency , we will design the radiator Length (L) of Antennas, as in Simple A Halfwave Principle Antenna Design .

For High Frequency, we used formula :

                                                                 L = 468/Fmhz 

Center Frequency of 470-800 MHz is 635 MHz

                                                                L = 468/635
                                                                 
                                                                   = 0.737 ft

                                                                   = 0.113 meter  (approximately)
                              
                                                                   = 11.3 cm

                                                          1/2L  = 5.65 cm

So, we will make 2 radiators using coaxial cable with length 5.65 cm each
