Antennas : 20M
- 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
[Hits: 47711 | Votes: 35 | Rate: 6.00] Antennas : 2M Antennas : 6M
- Omni-Directional antenna for 6-Meters
- Experimental omni-directional antennas for 6-meters band
[Hits: 8971 | Votes: 4 | Rate: 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.

- An almost Omni directional horizontal antenna for six meters by G8UBJ
[Hits: 2229 | Votes: 4 | Rate: 7.50] - K0FF's 6 meter SLOOP antenna
- It is more or less omni-directional, and horizontally polarized, it's just a dipole folded around on itself, and supported at the far (open) end with a plastic insulator.
[Hits: 2215 | Votes: 6 | Rate: 5.67] Antennas : Collinear
- Build a 2.4GHz Vertical antenna
pop
- Building a 2.4GHz vertical collinear omnidirectional antenna
[Hits: 62268 | Votes: 53 | Rate: 4.80] - 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.
[Hits: 6614 | Votes: 7 | Rate: 7.72] - Omni-Gain Vertical Collinear Antenna
- This rugged antenna, an omnidirectional collinear, is capable of surviving harsh environments. It's a good choice for repeater installations and can be top, or side mounted to the tower by WA6SVT
[Hits: 6914 | Votes: 4 | Rate: 5.25] - Home-brew Compact 6dBi Collinear Antenna
- This page details the construction of an easy-to-make collinear 360 degrees omni-directional, vertically polarised, antenna for 802.11b/g wireless networking.
[Hits: 14153 | Votes: 17 | Rate: 8.07] Antennas : Dipole
- Build a hanging dipole for 2 metres
- Described here is a simple omni-directional, vertically-polarized dipole for two meters. Made from coaxial cable, it can be rolled up and stored in a small container
[Hits: 4309 | Votes: 3 | Rate: 8.33] Antennas : Halo 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.
[Hits: 24887 | Votes: 22 | Rate: 7.11] Antennas : Loop
- 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.
[Hits: 4179 | Votes: 4 | Rate: 6.50] Antennas : Multiband
- CobWeb antenna construction
- A 5 band omni directional antenna original design by g3tpw. Works on 10,12,15,17,20,2,6 m & 70cms.

[Hits: 489 | Votes: 0 | Rate: 0.00] Operating Modes : Radio Direction Finding
- 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.
