Are you looking to boost your signal on the 70-centimeter band? Do you want to hit that distant repeater or perhaps even try your hand at satellite communication? Look no further! The 3-Element Yagi antenna is a fantastic project for any radio amateur looking for a reliable, high-gain directional antenna that’s surprisingly straightforward to build.
Yagi-Uda antenna (often just called a “Yagi”) is a directional antenna that uses multiple passive elements alongside a single driven element to achieve significant gain and directivity. This means your signal goes where you want it to go, rather than scattering in all directions, making it perfect for targeting specific stations or repeaters.
This particular design is a finely tuned beast for the UHF (Ultra High Frequency) band, specifically optimized for the popular 430-440 MHz segment used by amateur radio operators.
