Coaxial Collinear Antenna for 70 CM Band - This coaxial collinear antenna was built to test for my own consumption whether or not this antenna method actually works. the guiding principle is that we have multiple 1/4 wave elements fed in series , the radiation from each adds in phase to produce a large vertically polarised omni-directional antenna with substantial gain

Short Monoband Dipole Antennas - KGD Antennas - The KGD antenna is an option for those with space restrictions. The idea behing this project is to provide a short dipole antenna for HF Bands and to allow operations on HF bands when its not possible to setup large antennas, using these short base loaded dipoles.

Fan Dipoles 10/15/20m and 12/17/30m - How to build Fan-Dipoles by DK7ZB. Experiences with various band combinations. Not all combinations are working properly. If the frequencies are to close together the impedances will lead to a very bad SWR. This happens with the bands 10-12-15m or 15-17-20m.

History of the Hexbeam Antennas - The original HEXBEAM was developed by Mike Traffic, N1HXA, in the early nineties. It is true that an M over W configured yagi antenna that resembled a butterfly was earlier tried successfully. But the advanced electrical design, the characteristic nesting concept and central terminal post that enable the multi band functionality along with the basic hardware design were all developed by Mike Traffie.

Exploring The J-Pole Antenna - The J-Pole antenna is a common omnidirectional antenna used in amateur radio, particularly on the VHF and UHF bands. This article is an attempt to explore how the J-pole antenna transforms feed-line impedance to free-space impedance, all the while providing gain found only in the more expensive commercial products.

Semi-automatic antenna tuner project - Thsi article describes a microcontroller driven semi-automatic antenna tuner capable of handling power levels up to 150 watts. The device is a low pass filter tuner manually tuned by setting the optimized L/C combination by hand and then storing the values into the EEPROM of the mictrocontroller to recall them later (seperately for each band from 80 to 10 meters including WARC bands)

The ZS6BKW Multiband HF Antenna - This is the antenna for you guys who want to get on HF effectively, and haven’t too much space or cash to throw around. Actually, it’s a design from ZS6BKW (aka G0GSF), similar to the G5RV, but it actually resonates on five bands, (well 6, actually) and doesn’t rely on a tuner (ATU) to make it work.

A 3.5MHz Receiver for SSB and CW - Homemade receiver for 80 meters band. The receiver works very well (in fact better than some of its successors), especially the AGC makes listening to 80m QSOs a real pleasure. Sensitivity is not cutting-edge, but on a full-size short-wave antenna it is by fare sensitive enough.
