• Linear Loaded 40m Dipole - Dipole for 40m band. It is a simple linear loaded dipole feeded with 450-Ohm openwire feedline. Designed it for resonance at 7.050 MHz, can be tuned on 30m and 80m bands with an external antenna tuner. Build with simple electrical copper wire (2.5 mmq/13 awg) and two fishing poles with size of about 7 m/23 ft.

• 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.

• 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.
