## Frequently Asked Questions

To perform the Helicla antenna design calculation, users need to calculate all primary design parameters namely Operating Frequency, Helix Dimensions, Spacing between the turns, feed-point location, and impedance matching network. To quickly determine all the necessary helical antenna design parameters, then check out the above websites.

The helical formula is an equation used to calculate the length of a helical antenna. The formula is given by: L = C / f. Where L is the length of the helix, C is the circumference of the helix, and f is the frequency of operation.

The size of a helical antenna depends on the operating frequency and the desired performance specifications, such as gain and beamwidth. Generally, the length and diameter of a helical antenna increase as the operating frequency decreases. The length of a single-turn helical antenna can be approximated by the helical formula: L = (d * pi) / f, where L is the length of the helix, d is the diameter of the helix, and f is the operating frequency.

The separation between helical antenna turns is referred to as the spacing. The antenna's performance, including its impedance, gain, and radiation pattern, is influenced by the spacing, a crucial design factor. The operating frequency and helix diameter are typically used to calculate the distance between turns of a helical antenna. As a general rule of thumb, the helix's turns should be separated by one-quarter wavelength at the working frequency. With this distance, the feed line and antenna's impedance can be well matched.
