Cardioid (10m) The Cardioid Pattern antenna is designed using a two element vertical phased array architectecture. A pair of 5/8 wavelength radiating elements are driven with an optimised phase difference to produce the cardioid pattern....

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 performan...

GP Monopole with 256 Radials HamSphere 4.0 series of Vertical Monopole antennas are essentially 1/4 wl vertical antennas with groundplane radials. This is a classic antenna very commonly used by ham radio operators all around the world. ...

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 th...

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 band...

This is the Small version of the standard public Event Calendar. Operators can add Activations and NETs with different lengths and recurring dates and events are publicly shared with all operators having this plug-in installed. Hence it ...
