" The Perfect cb antenna" ?

Those SWR slaves...
What about reactance, radiation loss?

So, this is an antenna that is between 5.5 and 6 feet long and it uses a planar loading coil. All a planar coil is is a flat coil, nothing more.
They also loaded part of it up with, essentially, techno mumbo jumbo as read from the antennas manufacturer's literature.
MEG... It stands for Mean Effective Gain as stated in the video, and it is actually a thing, although I have never seen it used below the UHF range of frequencies, or on the CB or Ham bands... On HF where both antennas are vertically polarized, just think dBi gain and your 98% there. Oh, and 7 dB-MEG??? How was that antenna measured to get that number? For some reason, whenever I ask this all I get are crickets... I can go on here, but to be honest, this whole paragraph that was read is nothing more than technical mumbo jumbo likely quoted (or paraphrased) off of some technical document... Basically, long story short, they can't dazzle you with brilliance, so they chose the other option...
Also, I have modeled planar loading coils before, they don't performan noticeably different than a typical loading coil... While rare, this type of coil isn't exactly a new technology, if they even offered minor measurabe results over a standard loading coil, they would have been all the rage decades ago...

The perfect CB antenna if ever such a thing exists is most likely the 1/2 wave end fed vertical as high as possible.
No radials
Equals or beats the traditional design 5/8 wave when elevated to same tip height
Does not suffer from excessive CMC issues in most installs due to voltage fed.
Low price
Easier to set up and achieve low SWR for a beginner
5/8 wave loses its "in-phase" related ground reflection gain once elevated and the 1/2 wave matches or exceeds the 5/8 wave performance, as many 5/8 wave users do not have 4 x full 1/4 wavelength radials installed and never realize any gain at all.

This discussion may require a BBQ grill, rather large cooler, ice, lots of beer. So let's open up a bottle, start telling lies, calling up women.... Hope everyone got to see family and had a Merry Merry Christmas.
I "had" a compactenna dual band mobile antenna, that I had posed questions to the "manufacturer". I was given the run around and never a real answer. I opened the antenna radome, to see what was in there. It was a pathetic joke, that was nothing but snake oil. I would steer clear of this phonies wares.

Looks like a huge wind catcher Lol.
I'll stick with my tried and true 102" SS whip, or my Sirio 5000/Wilson 1000.
