How to make a GP Antenna

Amateur Radio in the quarter-wavelength antenna should be the most simple and the results are not that bad of a radio antenna in the world where it occupies a considerable proportion, for example if you pay attention to it most of the police car antenna a quarter wavelength antenna like you in the 430MHz mobile phone with its quarter-wave antenna are also there most of your attention to what the majority of cellular phones are also a quarter of mobile phone wavelength of the antenna can be seen a quarter-wavelength antenna has its effect is definitely there if you do not have the concept of e, then you might ask what is a quarter wavelength it? simple terms it is an antenna length of the unit is to calculate the frequency it has a formula:

Antenna length (wavelength) = 300 divided by frequency multiplied by 0.96 in the quarter (wavelength shortening) is

Are considered out of the antenna length (m) For example if you have to do a first frequency 144.00MHZ first calculate the antenna to the antenna length on the above formula: (300 / 144.00MHZ) * 0.25 * 0.96 = 0.5 (m)

So we get 0.5 meters is 50 centimeters in length should be prepared materials we are ready to come back five 50 cm copper bar and an M-Block connector (Figure 1) and M-type with a soldering iron to the spindle and one of them the copper strips welded together then spent another four screws on the sides or welding then four of the 45 degrees down

Kind of relatively simple method of making the GP antenna, connection and installation in several ways.
