Antennas
- The Antenna Elmer
- Here you will find information about wire antennas as well as directional beams.
[Hits: 7634 | Votes: 24 | Rate: 7.63] - Building an own Stackmatch
- Nowdays lots of people are putting up antennas to either beam in different directions at the same time or just to stack them and get a lower angle of radiation. Use this stackmatch to match you array.
[Hits: 601 | Votes: 1 | Rate: 8.00] Antennas : 15M
- The extended double zepp
- This wire antenna exhibits extraordinarily high gain in a bi directional radiation pattern.
[Hits: 10936 | Votes: 27 | Rate: 8.04] Antennas : 17M
- Aerialacts
- MaxiMoxon is aerialacts trade name for its line of compact, monoband, two-element, uni-directional parasitic beam antenna arrays utilizing Yagi-style aluminum elements. MaxiMoxon models are available for the 20, 17, 15, 12 and 10 meter amateur radio bands.
[Hits: 3410 | Votes: 5 | Rate: 2.40] 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: 47726 | Votes: 35 | Rate: 6.00] Antennas : 6M
- Omni-Directional antenna for 6-Meters
- Experimental omni-directional antennas for 6-meters band
[Hits: 8974 | 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.
[Hits: 26265 | Votes: 9 | Rate: 7.78] Antennas : 80M
- A magnetic loop antenna for HF
pop
- Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. Most parts needed can be purchased at a hardware shop. The antenna can be put together in an afternoon and requires only hand tools to assemble. It should cost less than sixty dollars to build.

[Hits: 68865 | Votes: 22 | Rate: 5.09] Antennas : Beverage
- Why terminate a Beverages
- Terminating the far end of the Beverage makes it unidirectional. It also makes the receiving angle of the antenna lower.
[Hits: 2233 | Votes: 0 | Rate: 0.00] - Comparison of Beverage antenna
- A ranking of receiving antennas based on noise being evenly distributed in all directions. These rankings are most accurate in the frequency range of AM broadcast, 160 or 80 meter bands
[Hits: 2226 | Votes: 2 | Rate: 6.50] Antennas : Collinear 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.

- A Simple Nondirectional Antenna for Ten Meters
QST February 1950, Easy to build J-Pole antenna for restricted space.
[Hits: 5254 | Votes: 1 | Rate: 1.00] Antennas : Shortwave
- Build your first dipole
- The dipole antenna is an easily designed and made antenna usually used on HF, although can be (and sometimes is) made for VHF and UHF antennas, and in varying forms is also used as part of different designs of antennas – i.e. as the driven element for directional antennas.
