2 Element Quarterwave Array: 2.9dB over Single PERformer!

This is the latest information I have on the quarterwave parasitic array. I explain its benefits and show how to set up the array. Greg KJ6ER helped me refine the design with his extensive modeling. I also briefly share some of his modeling results. I then take the array out to the park and try the 2-element and even set up a 3-element. The director is probably not spaced or tuned for max gain. I'll do more research and try to improve this in the future. Here are links to the tuning guide for the 2-Element (20m-6m): PNG: https://drive.google.com/file/d/1WwJ2... PDF: https://drive.google.com/file/d/1F83H... Thanks to Greg KJ6ER for all the work he's done on his antennas and sharing his knowledge and modeling with everyone. If you're not on his email list please reach out so you can get all his latest antenna designs. Next month he will be releasing more information on this 2-element parasitic array as well as new phased array. If you have anything to add or need to correct something I got wrong please feel free to leave a comment! 73 de K5OHY 00:00 - Intro 03:32 - Greg's Recommendations 05:03 - How to Deploy 08:11 - Park Introduction 12:59 - Single Element Setup 14:52 - Radials 19:06 - SWR Single PERformer & RBN Testing 19:48 - Director Setup 20:38 - SWR Director 21:22 - SWR Reflector 22:15 - Reflector Setup 24:20 - Activation Summary with 2 Element 24:33 - 3 Element SWR 25:25 - Hairpin 27:37 - SWR and Impedance After Hairpin 28:30 - 3 Element Activation Results 28:34 - Recap
