FAQ

Those interested in the 1 2 wave ground plane antenna calculator category often ask the following questions:

### ☑️ 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.

### ☑️ 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.

### ☑️ 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.

### ☑️ How to make a 1 2 wave cb antenna?

• For a quickie CB antenna, a vertical dipole (1/2) wave can be made right from the coax itself You take your coax and very carefully, without nicking the braided shield, strip 102 inches of the outer insulation jacket off one end. After removing the outer jacket, start bunching the shield down the coax from the end.

### How does a quarter wave antenna work?

The monopole is often used as a resonant antenna; the rod functions as an open resonator for radio waves, oscillating with standing waves of voltage and current along its length. Therefore the length of the antenna is determined by the wavelength of the radio waves it is used with.

### 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.

### 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.

### How does an antenna work voltage standing wave?

When an antenna is not matched to the receiver, power is reflected (so that the reflection coefficient, , is not zero). This causes a "reflected voltage wave", which creates standing waves along the transmission line. The result are the peaks and valleys as seen in Figure 1.
