Stationary, directional antennas (Yagi, X-Quad)

A directional antenna concentrates the field of radiation in one direction only, signals from other directions are picked up only weakly or not at all. The higher the gain of a directional antenna, the sharper the directivity pattern, the more precisely the antenna should be pointed.

For maximum range and performance, directional antennas are essential. Various designs - Yagi, X-Quad, Helix etc. - offer different advantages, depending on the application. Here it is important to find the most reasonable compromise between length and gain for the specific situation. Sometimes only the easy transportability plays a role, for example if you want to take an antenna and a small radio with you to the next mountain. By ‘stacking’ several directional antennas, the performance of Yagi antennas can be increased considerably, which is important for contests and more exotic applications such as EME. Of course, powerful directional antennas need a rotating system, i.e. an antenna rotor and a corresponding mast. WiMo will be happy to advise you here, as we also offer the necessary accessories such as low attenuation cables, rotors and distributors.

FAQ

How does a Yagi antenna work?
A Yagi antenna is a type of directional antenna that consists of a long element called a boom and several shorter elements arranged perpendicular to the boom. These elements are typically an active feed line (the dipole), one or more directors in front of the feed element, and a reflector behind the feed element. The Yagi antenna works on the principle of wave amplification, in which the dipole absorbs and radiates the signal. The directors help amplify the radiation of the signal in a particular direction while the reflector reflects the signal in the opposite direction, thus increasing the forward gain. This arrangement creates a directional pattern that allows the Yagi antenna to efficiently receive and transmit signals in a specific direction, making it particularly suitable for long-distance communications via amateur radio.

What is an FM directional antenna?
An FM directional antenna is a specialised antenna used to direct the signal from FM radio stations in a specific direction for better reception quality. This type of antenna is often used by people who live or work in areas with poor FM reception.

How does a directional FM antenna work?
A directional FM antenna works by directing the FM signal from one transmitter in a particular direction while blocking the signal from other directions. This is achieved by using special elements within the antenna to focus the signal in the desired direction.
