antenna gain shipped with the router

[ongbenghui]

Anyone know what is the gain of antennas shipped with AX88U and AX86U ?

The maximum allowed for the country where they are sold in, taking the RF amps and other important design choices and aspects into account.

(I would guess around 5dBi).

Omni directional antennas of that size are usually unity gain, i.e. none.

I believe the antenna gain can be found in the FCC radio test report. So for example the RT-AX88U document shows approximately 2dBi:

Speaking of antenna gain, I have seen taller antennas on Amazon that claim 9dbi gain.
@thiggins in your experience is there any real world advantage as far as better range with these?

Thanks for taking the time to look that up, Colin and bringing some fact to the discussion.

I have no experience with substituting antennas on routers. As has been noted, antennas are an integral part of the entire RF chain design. So I don't mess with them.

@ColinTaylor how would I search for the RT-AX86U, instead of the RT-AX88U, with your link? (What is the main site address)?

@ColinTaylor, thank you for that link. Half an hour later, I am still shocked by how ineffective that site is to navigate. Still don't know the identical information of the RT-AX86U vs. the RT-AX88U you presented above.

I haven't given up yet though.

For 'closure', I've given up.

That website is just a tangled web of spaghetti and all I want is soup!
