How do you calculate dipole frequency?
Dipole length formula Often a formula for the length of a dipole in feet is seen as 468 / frequency. This can be derived by taking the figure of 492 seen in the formula above and multiplying it by the typical A or end effect factor of 0.95.
How long is a 10m dipole antenna?
Member. A 10 meter dipole would be around 16 ft.
How long is a 20m dipole antenna?
20 Meter Dipole at 42 feet.
How long is a 60m dipole?
approximately 26.6 meters
Total length approximately 26.6 meters.
How long is a 40m dipole antenna?
The antenna isn’t really all that long, just 66 feet. The band is often open in the evening. Unlike 80m, which is full of nets, 40m is more open and you can call CQ and hope to get an answer.
What is dipole antenna length?
A dipole antenna consists of a conductor broken in the middle to allow it to be fed from a balanced transmission line. The total length of the dipole is normally one-half wavelength though other lengths are used in certain cases.
How high should my dipole be?
Recommendation. For best results, dipoles should be at least 1/2 wavelength above ground level. For the lower bands, especially 160-40 meters, this can become impractical–place your dipole as high as your situation allows.
How long is a 6 meter dipole antenna?
It’s small, only about 9 feet 4 inches from end to end, (see drawing below article) so it can be configured for other bands as well. I used the standard formula for a dipole (468 / Freq mhz = total feet. The lengths in the drawing below are for 50.1mhz.
How long is a 17 meter dipole?
The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. Place a 1:1 Balun on the Antenna end of the Feedline….Dipole Antenna Calculator.

How to calculate the length of a dipole antenna?
The Half-Wave Dipole Antenna. The most widely used formula to calculate the approximate overall length of wire required for a dipole is: 468 / frequency (MHz) = length of wire in feet. The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole.
Which is the correct frequency for ham radio dipoles?
The Antenna Calculator forHalf-Wave Dipoles Enter your desired frequency (MHz) of operation (i.e. 3.55). If you have no particular preference within a given ham radio band, then simply enter its center frequency (i.e. 7.15 for the 40 meter band).
How to calculate the length of a half wave antenna?
The Half-Wave Dipole Antenna The most widely used formula to calculate the approximate overall length of wire required for a dipoleis:468 / frequency (MHz) = length of wire in feet. The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole.
Is there an antenna calculator for a ham radio?
Here is a simple antenna calculator for two popular forms of ham radio HF wire antennas: the horizontal dipole and the inverted “V”. (Updated June 5, 2021)
