3 wire HF antenna 2 Mhz to 30 Mhz

A 3-Wire HF Antenna, covering the frequency range from 2 MHz to 30 MHz, is a type of broadband high-frequency (HF) antenna widely used in military, diplomatic, commercial, and amateur radio applications. Designed for wideband operation without the need for tuners, it is ideal for transmitting and receiving over long distances using skywave (ionospheric) propagation. The 3-wire configuration enhances bandwidth, improves impedance matching, and ensures greater durability under high-power transmission conditions.

The 3-wire HF antenna is typically a broadband, horizontal, center-fed antenna composed of three parallel conductors (wires) spaced equally apart and run in parallel over the desired length. It behaves as a terminated folded dipole and is well-known for its omnidirectional NVIS (Near Vertical Incidence Skywave) characteristics in lower bands and long-range DX capability in higher bands.
