Turnstile antenna is also known as crossed-dipole antenna as it consists of two identical dipole antennas mounted at right angles to each other. Currents fed to the dipoles are 90 degrees out of phase. Just like the helical antenna, turnstile antenna can have a normal mode in which it radiates horizontally [&hellip;]"}
