This is a commercially manufactured antenna with a gain of 9 dB, for 5 elements and 11 dB of gain, for 7 elements, according to the company that manufactures them.
Antenna Polarization Switch
A switch that would allow both horizontal, vertical, Left Hand Circular Polarization LHCP and Right Hand Circular Polarization RHCP for the 2x6 elements DK7ZB cross yagi that I made
