Ever wondered what's inside a wifi antenna? Here's some pics.

I've always wondered about these big antennas on routers. Wondered if it was a gimmick having big antennas, anyway I had the opportunity to teardown some antennas on some Asus AX routers I happened to be fixing.

Was surprised that they don't even put the actual antenna at the top of the tube.... What kind of BS is this Asus?

That's funny. You'd think the 5GHz rod would be 2X longer than the 2.4GHz rod, not the other way around. heheh

Twice the frequency means half the wavelength. That said, most of our Asus routers have Dipoles inside the plastic housing (unless things have changed). If you look at business class access points you'll see different antenna configurations again! The design is pretty simple and straight forward in most cases though!

Dosen't work like that, the higher the frequency, the shorter the wavelength of the dipole. I know you're joking though

I'm just very surprised they don't mount the antenna at the top of the tube as that would have a clear advantage.

Marketing. Bigger antennas, red/gold accents, RGB lights, etc. on the consumer market are seen as better.
