Give me a length. As the actress said to the...


This formula will get you very close to the resonant frequency you have selected. Do bear in mind that there are other factors such as wire size, height above ground and ground conductivity that can affect the overall length. Cut the dipole slightly longer than the calculated length and trim for the best SWR.

Enter Frequency in Mhz

Total length of dipole is feet or feet per side

Total length of Inverted V is feet or feet per side
