Seems like a rippoff to me.

Sieb.


The price is not terrible for an antenna and wifi adapter, however a
4.5dbi gain antenna is a little weak. But that depends on your
application, sometimes you don't want a tight beamwidth. There are
plenty of cheaper high gain antennas that you can buy
and connect a wifi adapter to.

Here's a 14dbi gain antenna for $40

Here's a wifi adapter that gets great reviews, I use one.
ALFA AWUS036H for $27

Just add a cable to connect them.

There 100s of more antennas to choose from.

dBi is a trick. Subtract 2.5 from the gain figure. Also, I think the OP
antenna was an omni, the panel antenna is directional.

I don't consider dbi a trick, just another standard of measurement.
If you use dbd you are comparing to a dipole which has 2.15 db gain over
an isotropic antenna. (I think you transposed to get your 2.5)

I think the OP antenna was an omni, the panel antenna is directional.

Yes, however even the omni is directional, but in the vertical direction
vs horizontal. There are higher gain omni antennas available.

That's why I added,
"But that depends on your application, sometimes you don't want a tight
beamwidth"
Probably all for naught, the OP seems to have gone on to other things.
