Stacked TripleFeed ("pagoda") Patch Array for FPV

Following the release of the famous open-source "Pagoda" antenna by Maarten Baert in 2016, a circularly-polarized omni antenna for 5.8g FPV which truly challenged the "Clover leaf" antenna specs-wise as the dominator of drone video transmitter's antenna, Maarten and Robin Theunis came up with the 5.8g circularly-polarized directional antenna called the 5.8g Triple-feed Patch in 2017, which challenged the very popular "Cross-hair" antenna's place as the best video receiver's antenna. Here, I present to you a stacked array of two Triple-feed Patches which offers a bigger horizontal beam-width and higher gain than a single Triple-feed patch. Attached is the STL file for the bezel to hold the two patches in a vertical array arrangement which is essential for wide horizontal beam. Also provided here, is the step-by-step video tutorial to phase two Triple-feed patches accurately to achieve similar results like an expensive Mini-Circuits 5.8g 2way splitter.
