GP antenna makes a method

In radio of Yu of course of study the antenna of 1/4 wavelengh should be a kind of antenna with the simplest and not poor also effect the antenna that if so it has scale of quite a few to if you have an attention,cite a case in radio group, the antenna on patron wagon is 1/4 wavelengh for the most part resembles is you. What is if are you the word that has an idea to electronic respect,you perhaps can ask 1/4 wavelengh? Simple for it is unit of an antenna length be will calculate with frequency it has a formula:

The length of aerial (wavelengh) = 300 is divided multiply with frequency on 1/4 multiplying on 0.96(wavelengh shortens rate) namely

Be calculated come out the length of aerial (unit meter) cite a case for if you want to do the antenna of 144.00MHZ of a frequency to want above all first length of cipher out antenna calculates with respect to the formula of above face: (Meter of 300 / 144.00MHZ) * 0.25 * 0.96 = 0.5 ()

So we receive 0.5 meters namely the length of 50 centimeters is about to prepare data again the copper that we prepare 5 50 centimeter with a M model contact (the 1) that be like a graph like that after uses iron M model main shaft and among them copper

Kind of simpler GP antenna makes a method, outfit receive a method to have several kinds.
