FAQ

Those interested in the 5 8 wave antenna radiation pattern category often ask the following questions:

☑️ 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.

☑️ How big is a 5 / 8 wave antenna?

  • This 5/8 wave (physical & electrical) antenna has a nominal impedance of 50-52 ohms and can achieve average tuned SWR of 1.5 to 1 over 4 MHz. The over all length is 48.2" (122.4cm). Gain over isotropic is 6 dB. Gain over 1/4 wave is 3 dB.

☑️ What is the equation for radiation pattern of a half wave dipole antenna?

E=sin(Theta); You need to normalize the equation for the electric field of the half-wavelegnth dipole. recall E=sqrt(ExE*) where E* is the conjugate of the E field. This is why you only get an eight shaped figure (or infinity symbol) when you plot it. you will get this figure if the dipole is placed in the axis of interest. e.g. if it is in the placed in the x axis, you will get an eighth in the x-y,x-z, but you will get a donut shape in the y-z (no angle to measure) hope this helps a bit.

☑️ How big is a 5 / 8 wave vertical antenna?

  • As a vertical monopole antenna is half the length of a dipole, this equates to about a five eighths wavelength vertical monopole antenna. When used as a vertical radiator against a ground plane this translates to a length of 5/8 wavelength.

☑️ What is the gain of a 5 / 8 wave antenna?

  • A quarter wave ground plane antenna has a radiation pattern that produces maximum gain at about 25 degrees and a half wave antenna drops that angle to 20 degrees, and the 5/8 wave antenna further drops that angle to 16 degrees.

How does a quarter wave antenna work?

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.
