According to the manufacturer it is the equivalent of an 18 to 24 element yagi. This statement by a company that manufactures all sorts of yagis…
(I mentioned the specific technical design in another thread) -
I first encountered the “Antop” type antenna a few years ago. It was manufactured by the Qiaohua\Shenzen company and sold through different distributors under different brand names. The “Eaglestar” brand was the first I came across 6 years ago.
At that time it was a a “slotted waveguide” design used in cellphone tower antennas, More on this antenna type here:

You already know my impressions of Antop and of that antenna in specific.

The AT-400 series is excellent! I got the 400BV, but did not install the (VHF) crossbars, as I was already getting 50-plus stations.
With limited technical knowledge and no experience in antenna TV, I ended up getting the Antop AT-400B. I realize the more conventional types (Yagi design, etc.) are great choices and that companies such as Channel Master and Clearstream make great antenna product. After a bit of research, I landed on the Antop, primarily because it would look so nice in my living room. It pulled in more stations than what my leaf antenna had, which made me wonder “what would this be like if mounted on the roof…
