omni antanna

20m delta loop  ^pop - This antenna is fed for vertical polarisation, to give a low angle of radiation for DX and also a nearly omni-directional radiation pattern

Omni-Directional antenna for 6-Meters - Experimental omni-directional antennas for 6-meters band

50MHz J-Pole Antenna  ^pop - Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

Build a 2.4GHz Vertical antenna  ^pop - Building a 2.4GHz vertical collinear omnidirectional antenna

EH Antenna QRP tests - A QRP test with the EH antenna for 27 MHz

6 meter omni halo  ^pop - This halo is made with a true Gamma Section this time and is fashioned from aluminum

Stacked Halos antennas - Stacked halo antennas for omnidirectional coverage by W9KXG

J-Pole theory  ^pop - The J-Pole antenna is an omnidirectional antenna that can be used for base, mobile and field day stations. It does not need a ground plane, radials or a complicated matching system. The J-Pole can be cheaply, simply and quickly constructed using a variety of techniques, some of which are discussed in this article.

The full-wave loop antenna - These omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.

Parabolic Discone antenna - This is the highest gain omni design the world may ever know having wide bandwidth

Common vhf amateur radio antennas - Plans and drawings of common amateur radio antennas, like jpoles, copper cactus, super jpole, omnidirectionals and quads

Omnicor - Vacuum Capacitors - Omnicor supplies Meivac vacuum fixed and variable vacuum capacitors for RF transmitters.

A new method of radio direction finding Priority listing - A method of finding radio sources with antennas based on omni-directionality (the less directional the better coverage). Uses energy levels and some sophisticated math (encompassed in a free software download on the site) to find x,y,z coordinates of the fox relative to the center of your antenna array. Can be overlayed on a GPS map to help you locate in real-time.

Omnilog - Logging program which offers control of your KENWOOD, ICOM, TEN-TEC , or YAESU (FT840, FT900, FT990, FT1000, FT1000D) radios directly from your keyboard or emulation of any of the above radios.
