Antennas : 2M Antennas : 6M
  • Omni-Directional antenna for 6-Meters - Experimental omni-directional antennas for 6-meters band
    [ Hits: 11126 | Votes: 4 | Rating: 4.75 ]
  • 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.

Antennas : Collinear
  • Build a 2.4GHz Vertical antenna  pop - Building a 2.4GHz vertical collinear omnidirectional antenna
    [ Hits: 73102 | Votes: 87 | Rating: 4.99 ]
  • The Simple Collinear - Wherever there is a need for a vertically polarized omni-directional antenna with gain, a collinear is used. The vertically polarized collinear takes the form of two or more half waves in-line and in-phase, resulting in an omni-directional pattern with maximum radiation near the horizon.

Antennas : Halo
  • Stacked Halos antennas - Stacked halo antennas for omnidirectional coverage by W9KXG
    [ Hits: 1911 | Votes: 2 | Rating: 10.00 ]
  • A 144 MHz Halo - This halo antenna was built to have an omnidirectional coverage while working in VHF contests. The idea was to have a small but useful antenna for receiving, but it has demonstrated very capable on TX also.

Antennas : J-Pole
  • 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.
