What antenna length is 433MHz?
for 433MHz frequency using a ¼ wave whip the ideal length is ~173mm as a straight length . Not more and not less. Shorter or longer will still work but if it is not an exact ¼ wavlength the antenna impedance changes and you do not transmit the maximum power.
What length should my antenna be?
The most effective antenna has the same length as the length of the wave it is used for. For practical purposes, half or a quarter of that length will suffice.
How do you find the length of a dipole antenna?
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.
What length should a 2.4 Ghz antenna be?
The length of the antenna on a typical 2.4GHz receiver is 28.8 to 32 mm long, most are about 28.8 mm. The antenna is that length of bare line often at the end of a longer coaxial cable to move the antenna farther out from the receiver.
What is the relationship between frequency and antenna length?
The higher the frequency the smaller the wavelength and the antenna length. C ( speed of light ) = lambda ( wavelength ) * operating frequency.

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 |
What is the length of a quarter wave antenna?
3 to 6 inches
Since the UHF band covers a much larger range of frequencies than VHF, 1/4-wave antennas can range anywhere from 3 to 6 inches (7-15 cm) in length, so using the proper length antenna is somewhat more important. For a system operating at 500 MHz, a 1/4-wave antenna should be about 6 inches (15 cm).
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.
