Hi everyone, my quad helix broke again, so I started work on a simple FR4 PCB patch antenna. To make the size practical, it is designed for 1/5 wave length and it would require the use of a good LNA and with no rotator needed. So, it would be small, mechanically simple, unobtrusive, wife and neighbour friendly. If anyone is interested, please let me know, then I will make a few extra.
