This antenna is an innovation. . ( I have read about a sloping two band Delta loop but it used two feed lines-- mine uses one). It is called the 40/30 pyramid. This antenna is predicated on what I will call ZO's law. That is, If rf can find resonance in an antenna, it will. I learned that on my fan verticals ( see my article on the fan vertical) .

    patch antennas are sometimes referred to as planar antennas. Figure 1 shows a patch antenna in its basic form: a flat plate over a ground plane. This antenna is often built of printed circuit board material and the substrate makes up the patch antenna’s dielectric. The distance between the patch and the ground plane – the Try using some quiet antenna like vertical delta loop or quad. You can use separate antenna for TX and RX.

    The antenna uses two Delta Loops with a reversible beam direction to provide a 360 degree coverage. A unique feature of the K9AY, is the Remote Controlled Variable Termination. This allows the user to optimise the null during changes in the arrival angle of interfering signals and provides a considerable improvement in reception quality.

    Equilateral Delta Loop : Full One-Wavelength Loop : Over level ground, the minimum mounting height for the apex of a Delta Loop is the altitude plus the height of the support posts. If the loop is an equilateral triangle as shown, the Minimum Horizontal Spread = the length of one side plus the distance to the tie off points (support posts).Delta Loop Antenna. A full-size Delta Loop, fed in the bottom corner, is a good low angle radiator and is great for working DX. This antenna normally has about a 3 DB gain over a 1/2 wave center fed dipole. The Delta Loop is not only a great transmitting antenna but a low noise receiving antenna. The direction of fire is broadside to the antenna.
