For the Citizen Band, due to potency limitation, it falls to the operator the largest care in the treatment of your system irradiante.
Already for I Radiate them amateurs the thing it is a little easier in if treating of dipolos or even a Zeppelin or Bazooca. For whole and any antenna type is just enough to follow the calculations and to use always of good sense.
The calculation for all and any antenna is basically the same or be: 142,5/F. With the result, we obtain a DIPOLE of half wave. Now, so that we can have a dipole of half wave, we divided the value found by 2.
As example, we will take the frequency of 7.150Mhz, in the 40 Meters band.
We go there: becoming be divided 142,5 / 7.150, we will have = 19,93m, that is the antenna of half wave and, so that we have the dipolo, it is enough to divide the found value - 19,93m - for two and, like this, we will have our dipolo for us to begin even that big directional antenna.
With more peacefulness, I will place drawings of antennas so that all can enjoy the ham-radio well.
