I'm interested in erecting a #20meter #4square #VerticalPhasedAntennaArray for #HamRadio but haven't found anyone who makes one. Probably have to build it myself.
So far, my searches of the web haven't turned up anything. I get the reason is a 20m yagi is reasonable for most, but I'm disallowed a tower. But I've enough space on ground for phased verticals.
Any of my fellow #FediHams know of one?
Just look at 40m & math out the differences?
