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 high is 40m dipole?

The dipole was modeled at various heights from . 05 wavelengths (7 feet) to 4 wavelengths (560 feet) above good ground. One may argue that 560 feet is ridiculous for a 40 meter dipole, but keep in mind that the data can be scaled down to a 10 meter dipole with similar results.

What is dipole antenna length?

The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2). Such an antenna is called as half-wave dipole antenna. This is the most widely used antenna because of its advantages.

How high should a 40 meter antenna 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 does an 80 meter dipole need to be?

thirty-five feet
At a height of thirty-five feet, the 80 meter dipole constructed according to the classic formula and directly fed with 50 ohm coax exhibits a better SWR of 1.1:1 at resonance, but has a 2:1 bandwidth of about 150 kilohertz and a 1.5:1 bandwidth of only 100 kilohertz.

How long is A 60 meter dipole antenna?

approximately 26.6 meters
Total length approximately 26.6 meters.

How long is A 10 meter 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.
