DIAMOND WD330

DIAMOND WD330 T2FD

The WD330 T2FD broadband dipole antenna is designed to provide optimum performance over a wide frequency range. Its unique broadband design eliminates the need for multiple antennas or external antenna tuners, ensuring consistent operation from a single installation.
A key advantage of the T2FD concept is its low noise floor, which often provides better overall reception quality than pure signal strength—especially in challenging HF environments.

Key Facts

  • HF wideband, 2-30 MHz
  • Low noise
  • Passive
  • No static interference
  • No antenna tuner required
  • Can be installed horizontally for maximum efficiency, but also as an inverted "V" and as a sloper.

Overview

DIAMOND WD330 T2FD

A T2FD antenna (Tilted Terminated Folded Dipole) is a wideband, low‑noise HF antenna known for stable performance across a very large frequency range.

A T2FD is a folded dipole antenna that is:

  • Tilted (installed at an angle)
  • Terminated with a resistor
  • Broadband (very wide frequency coverage)

It typically consists of:

  • Two parallel wires forming a folded dipole
  • A terminating resistor at the far end
  • A balun at the feed point
