    1 / 4 wave GP antenna

     

    Quarter wavelength in the amateur radio antenna in the most simple and effective should be regarded as no less an antenna in the radio sector, so it holds quite a lot in the proportion of for example, if you have the attention of police on the antenna, then most of quarter wavelength of the antenna like your cell phone with the 430MHZ most of its antenna are also there to your attention about a quarter wavelength of the majority of cellular phones, are also a quarter wavelength The antenna can be seen a quarter wavelength antenna has its effect definitely exists. If you do not have the concept of electronic if you might ask what is a quarter wavelength it? simple terms it is an antenna length unit is to calculate the frequency it has a formula:
    Antenna length (wavelength) = 300 divided by the frequency multiplied by the quarter of 0.96 (wavelength shortening) is
    Be called out by the length of the antenna (in meters) For example if you do a frequency 144.00MHZ first calculate the first antenna to the antenna length on the above formula: (300 / 144.00MHZ) * 0.25 * 0.96 = 0.5 (M)
    Be 0.5M (50CM) the length of the preparation 5 50CM copper bar and a M-Block, the joint (Figure 1)

    Then use the iron to the main axis and one M-1 copper then be welded to the other four pieces of screws or welding on the sides of the then 4 down 45 degrees (Figure 2)

    The top of the main oscillator, a ring bending, so you can easily hang outside or the roof.

    Used above is an M-type female, M male feeders connected directly to screw in the female head, very convenient.

    In this way, we can create a variety of simple small antenna, such as working in the FM 98Mhz FM antenna, the oscillator length is only 74cm, very lightweight. FM transmitter for fans to produce their own.
