W3EDP End fed (10-40m) In 1936, Yardley Beers, W3AWH, described an empirically-derived antenna "designed by the writer's friend, Mr. H. J. Siegel, W3EDP."  It consisted of an 84 foot radiator and a 17 foot "counterpoise."  The design has lasted through the years. .  The W3EDP End-fed antenna is...

Double Zepp The Double Zepp (Doublet) antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. It covers 7 bands, 10-12-15-17-20-40-80m. Unlike typical antennas, this is a non-resonant antenna. The performance characteristics are quite outstanding. The antenna consists of symmetrical horizontal radiating e...

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...
