It looks like they copied parts of the Ubiquiti sectors and Omnis and forgot the horizontal polarity part.

So... I opened it up to see if there was an obvious reason it's so much worse than the other dual polarity omnis I've used, and it is indeed very different... I'm no antenna expert, but something seems very wrong with this design. Why would they even make something that works that poorly?[cid:[email protected]]
