By the way has anybody tried to put two FEEDs at 90 degrees on a regular dish (parabolic) ? (MiMo)...?

also puzzled by this question. I asked it to the admin in the topic about butwing

the thing is ...: how much shadow they cast (yagis need less area) (this bow-tie shapes need a LOT of REFLECTOR to work right...)

PS: i'm inclined to the PETRA designhttps://www.wifi-antennas.com/topic/478-petra-lite-box-home/#comment-3785...is amazingly smooth on ALL the bands...(but then again they need a lot of reflector AREA)

[Moved from the Biquad Antenna]

Taking in account it's for an offset mirror, would having more directors improve anything? I've noticed there is the slightly bigger 3G antenna. It would be cool to reach more than 25 dBi gain.

I understand that it's about the system in a whole. The higher gain of the feed antenna doesn't mean better system when placed in the focus of a parabola.

If the reason why the simple Bester is better is not because it's easier to build, but rather it results in better antenna, I'll be happy with it. But if the antennas with higher directivity may help to achieve more gain in an offset mirror, the build complexity must not be an issue either. My experiment is about setting kind of a record for Bluetooth Long Range, so I really don't want to loose those extra 3 to 6 dB from the link budget if I can :-)

So which one is best, the simple Bester or the original Bester?

,,, good, but why not try to put a Batwing antenna in the focus of the  offset mirror...????

Why not? I'm open to any solution.

By the way, to me the Batwing antenna looks like a biquad modification. From the simulation data it doesn't look superior to the biquad though, except it has slightly wider bandwidth.
