30 lip 2024 · Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
DIPOLE CALCULATOR. Imperial. Metric. Enter your desired frequency in MHz. After setting up your dipole with the lengths listed to the right, retest the SWR, find the frequency with the lowest SWR and enter that frequency in MHz below.
Almost any kind of antenna will radiate a signal, but the antenna is not good if it does not radiate enough signal or if it sends the signal off in the wrong direction. Our purpose here is to discuss only those features of radio wave transmission that have some bearing on the installation and maintenance of a high-frequency (HF) antenna system.
Dipole Antenna Calculator. The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun.
6 maj 2023 · for a Dipole or Inverted Vee Antenna. This calculator uses a "K" multiplying factor value of .975 to adjust for the effect of antenna wire diameter on length which is applied to the free-space half-wavelength equation. This works very well with #18 to #12 wire sizes. Enter the Frequency in MHz.
