While researching the qha, I wanted something easier for checking out circular polarization. I discovered that 70% of all commercial FM radio stations run circular polarization. Home receivers are usually horizontal while mobiles are vertical. After looking up the types of antennas they use, I came up with two designs. The first has as much gain as a QHA but is much easier to build. I recommend...

How to construct a helcal wound loop, 2 element helical loop. Most of the authors designs are much longer in wavelength, each loop of the 2 element designs actually have maximum performance at a percentage of wavelength approaching between 1/3rd & 1/2 wavelength each loop. Thus termed Fractional wave vs magnetic loop. Therefore the constant current usually referred to in a magnetic loop no...

The driven element can be either as an electrically separate dipole or together with the boom and the other elements, as a gamma match. When several parasitic antennas are operated together, such as in a collinear or stacked array, there are several driven elements. Each driven element receives a portion of the output power of the transmitter. Generally, the power is divided equally among all...

Thanks to Aire for 4nec2 which is an exceptionally well done piece of antenna modeling freeware. Undoubtedly the best implementation of the Parabolic Template Design I've seen so far. Thanks to Jem E. Berkes for DIR2HTML. Jem writes a number of nice utilities. Very interesting way to build a parabolic. Parabola Builder. (c) M. Erskine 2002-2015 All Commercial Rights Reserved.
