## How long should my dipole antenna be?

When determining how long to make each leg of a Dipole antenna, dividing the frequency in MHz into 468 will give the overall length. To find the half wave, divide that number by two. This will give you the length of each leg of the antenna.

### How do you find the length of a dipole?

Dipole length formula

1. length (metres)=150 Af.
2. length (inches)=5905 Af.
3. length (feet)=492 Af.

How long is a 10m 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. Place a 1:1 Balun on the Antenna end of the Feedline….Dipole Antenna Calculator.

28.500 16.42 8.21
29.000 16.14 8.07

What is the length of a dipole at 2.4 GHz?

0.35 λ
We found that the length of the dipole antenna for the 2.4 GHz frequency is 0.35 λ, and the balun length is 0.25λ for the bazooka and 0.2 λ for the 1: 1 balun.

## How long is a 20 meter dipole antenna?

Approximate Lengths for HF Ham Band Dipole Antennas
Band (MHz) Length (Feet) Length (metres)
7.0 MHz (40 metres) 68.5 21.1
10.1 (30 metres) 47.5 14.7
14.00 (20 metres) 34.3 10.6

### How long is a 40m dipole antenna?

For several reasons: 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.

How high off the ground should a 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 high should a dipole be off the ground?

## What are the dimensions of a dipole antenna?

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. Place a 1:1 Balun on the Antenna end of the Feedline.

### Which is the best dipole antenna for a ham radio station?

As Bob KØNR mentions in Shack Talk, Your First Dipole Antenna, erecting an antenna for HF operations is perhaps the most challenging aspect of establishing a basic HF station. The horizontal wire, half-wave dipole antenna is one of the simplest HF antennas to set up, it offers very good performance, and that makes it a very popular choice for hams.

How to calculate the wavelength of a dipole?

Wavelength, as well as its portions: 1/2, 1/4 (it’ll also allow you to use it as a 1/2 wave dipole calculator). You may enter the diameter of your conductor to obtain the adjustment factor [k]. You may need it for high frequencies and thick wires, or if your antenna will be made out of the tube.

What’s the best way to shorten a dipole antenna?

In practice it’s best to make the antenna a little longer than the calculated value and then trim it to get the best SWR value. Shorten your dipole antenna using the Coil-Shortened Dipole Antenna Calculator .

How long should my dipole antenna be? When determining how long to make each leg of a Dipole antenna, dividing the frequency in MHz into 468 will give the overall length. To find the half wave, divide that number by two. This will give you the length of each leg of the antenna. How do…
