FAQ

Those interested in the 5 8 wave ground plane antenna calculator category often ask the following questions:

☑️ How to make a quarter wave ground plane antenna?

What is the formula for quarter wave antenna?

  • Figure 2. - a marconi antenna. The formula for quarter wave is L = 71.25 metres / freq (mhz) and in feet L = 234 / freq (mhz). Note the variance from the standard wavelength formula of 300 / freq. This is because we allow for "velocity factor" of 5% and our wavelength formula becomes 285 / freq.

☑️ Does a 5'8 wave antenna need a ground plane?

The absence of a ground plane or very small ground plane will cause the matching circuit for the 5/8 wave to be a little different due to less capacitance between the vertical element and the ground plane, otherwise there is no "reflection or radiation from a second source" to produce gain in a 5/8 wavelength antenna.

☑️ Does a 1/4 wave antenna need a ground plane?

Does a 1/4 wave antenna need a ground plane? Answer: Yes. All 1/4 wave antennas work best if they are installed in the center of a metal ground plane with at least 1/4 wave length radius (1/2 wave length diameter: ~6 inches for 900Mhz and ~3 inches for 2.4Ghz); larger is better.

☑️ Does a 1/2 wave antenna need a ground plane?

Does a 1/2 wave antenna need a ground plane? Answer: No… It does not require a ground plane to work efficiently. In fact it is best to install the 1/2 wave antenna at least 8 inches from any nearby metal objects for better performance.

☑️ Can a 5 / 8 wave antenna be fudged?

  • With a 5/8 wave antenna the 'starting' impedance isn't anywhere close to where it can be 'fudged' by just tilting the radials. You have to do that 'matching' of impedances by some other method. Those 'other methods' include both capacitive and inductive reactances, you can do it with either a capacitor or a coil.

Why does wave length of antenna matter?

This frequency is determined by the length of the antenna and the speed of light in the antenna material. In this resonant condition, the electrons' motion and the incoming electric field are always in the same direction, so every wavelength of the EM wave builds up more motion and puts more energy into the antenna.

Relation between wave length and size of the antenna?

If the same signal is modulated to some high frequency say 88 MHZ ( λ = 3.4 m ) , antenna height needed is 0.8522 m (quite easy to construct !!! ) (88 MHZ is the starting range of Frequency modulation which exists upto 108 MHZ).
