In general, I am a bit disappointed that there have not been any major breakthroughs in antenna design for television over the last 50 or 60 years. I guess its just physics and funding holding things back. Most new antennas are just re-marketed as HD antennas and some are not much better than rabbit ears with bad amplifiers.
I am comparing antenna progress to the revolution in television technology. From black and white round tv tubes to computerized hd flat screen digital sets today. There are many cm4228 and clones around today but these are just an array of bowties that have been around forever.
Where is the Steve Jobs of antennas to come up with something really innovative. Perhaps we need computerized, intelligent amplifiers mounted at the antenna mast?
