Diamond WD-330S | Broadband HF Terminated Folded Dipole Antenna

The Diamond WD-330S is a commercial-grade HF antenna designed for wideband operation from 2 to 28.6 MHz. Built on the T2FD (Tilted Terminated Folded Dipole) principle, it offers consistent impedance and directional radiation across a broad frequency range—ideal for amateur and professional HF communication.

Delivered fully assembled and pre-tuned, the WD-330S eliminates the need for measuring or cutting during installation. It features PVC-covered stranded copper wire, fibreglass spreaders, a matching network, and a balun, with a 25m rope included for flexible mounting.
