T2FD Broadband Antenna (10-40m) The Tilted Terminated Folded Dipole (T2FD or TTFD) or Balanced Termination, Folded Dipole (BTFD) - also known as W3HH antenna - is a general-purpose shortwave antenna developed in the late 1940s by the United States Navy. It performs reasonably well over a broad frequency range, without marked ...

Fritzel FD4 OCF Dipole Fritzel FD4 OCF Dipole The Frizel FD4 Windom is an OCF (Off Centre Fed) antenna that has been around for a long time. The original Windom antenna (devised in 1928-29), named after Loren Windom, W8GZ. The Fritzel FD4 antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. It cover...

New Carolina Windom The New Carolina Windom antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. It covers 6 bands, 10-12-15-17-20-40m. Unlike typical antennas, this is a non-resonant, Off Center Fed Dipole (OCFD) antenna. The performance characteristics are quite outstanding. The antenna consists of a...

Sporadic E or Es is an unusual form of radio propagation using characteristics of the Earth's ionosphere. Communication distances of 800–2200 km can occur using a single Es cloud. As its name suggests, sporadic E is an abnormal event, but can happen at almost any time; it does, however, display s...

VU2NSB OmniDX Antenna series is a very special set of monoband antennas that have been designed from the core keeping in mind the optimal radiation lobe pattern characteristics needed for good DX as well as medium range operation on HF bands. Unlike Yagis, Quads, etc, where the antennas structure determines the expected radiation patterns...
