Description

Yagi antennas are directional, high-gain antennas widely used for UHF (300 MHz–3 GHz) and VHF (30–300 MHz) applications, including TV broadcasting, amateur radio (HAM), emergency communications, and military use. Below is a detailed breakdown of their design, types, and best-use cases. 1. Key Features of UHF/VHF Yagi Antennas ✔ Frequency Range: VHF: 30–300 MHz (e.g., FM radio, HAM 2m band [144–148 MHz]). UHF: 300 MHz–3 GHz (e.g., TV broadcasting, HAM 70cm band [420–450 MHz], public safety radios). ✔ Directional Gain: 6–20 dBi (depends on element count). ✔ Polarization: Typically horizontal (for TV/HAM) or vertical (for mobile/emergency comms). ✔ Durability: Aluminum/glass fiber construction for weather resistance.
