I saw that video and chameleon is doing similar product and I similar way but overall quality much better.
Is it worth the price ? Don’t know.
But for sure any kind of magic boxes are pure marketing and selling argument.
Apart nice packaging and machining stuff than you can’t do alone without tools
there is nothing really you can’t do yourself.
And experimenting with antennas is much easier than building transceiver from scratch or from kit.
Still fun and happier building one than spending lot for “commercial” antenna.
