RB2011UiAS-2HnD-IN antenna

Hi,

I am the owner of two RB2011UiAS-2HnD-IN routers.

I would like to “upgrade” the antennas but i don’t know to much about wifi.

Can you please advice me what kind of antenna should i buy?

In router’s specifications says:
Antenna gain DBI 4dbi
TX power 30dBm

what would you think about :

2x - +9.5dBi Omni TurboTenna 2.4GHz WiFi antenna with RP-SMA for Netgear
or
2x - 2.4GHz 15dBi RP-SMA Male Connector Tilt-Swivel Wireless WiFi Router Antenna

Would one of these 2 will extend my wifi range considerably?

Thanks in advance,

Remember: more gain, more noise…

Strictly speaking more gain does not always mean more noise, a better matched antenna circuit will have reduced noise in comparison to gain.

4

“not always more noise”: you admit than sometimes happen…

5

Yes correct but also you must admit there is much better antenna performance if you have a better matched RF circuit.

6

Yes, is also true this, obviously, but it only want change antenna. :astonished:

The OP just wants to increase coverage but simply attaching another antenna, even with higher specifications, this may or may not increase coverage, a comparison (sorry for this?) is like someone suggesting increasing engine size but not changing gearbox and many other items … to make a “Ferrari” go faster… sorry I meant to type “Tractor”

If you want to cover blank places of your flat, use other ap connected to main router by cable. It will be much more efficient than making antennas bigger. Otherwise explain in details what your goal really is.

I have perfect coverage in the house, except the balcony (after i close the door). I don’t know what this glass have in it, but after i close the door to the balcony, my signal drops from -45 to -90.

I have another AP via cable near the widnow (TP-Link TL-WR1043ND - 3 antenas), but the signal is even low than the RB2011UiAS router which is located in the middle of the house (i cannot change the location of the RB2011UiAS).

I thought that if i change the antenas to RB2011UiAS i will have stronger signal on the balcony after i close the door.

BTW, does anyone knows what is in these glasses that signal will not pass through? The wall between leaving room and balcony is all made of glass, and as i said, when i close the door to the balcony, signal drop almost completely.

I cannot put the TP Link router in the balcony.

The RB2011UiAS’s antenna has 4dbi. My logic tell’s me that if i add a bigger antena, with the current emitter form the router, the signal will be stronger, and more signal will pass through that glass. Maybe my logic is wrong, and that’s why i asked you guys.

The correct question would be: What is the biggest antenna that RB2011UiAS support it and it is compatible with?

Thanks in advance,

There is probably some metal in the glass to reflect heat. You can put whatever antenna but it will not help much thru your balcony door if it attenuates by 45 db there is no antenna it can compensate. What is more, you would destroy all connectivity inside the flat. Ideal signal level is around -60. Heaving more than -40 is causing serous problems so do not try to amplify the signal by bigger antennas. If you really need, small ap on the balcony with different frequency and low transmitt power would be the solution. I know you did not want to read this.

And also you must consider the DEVICE used, not only the AP, must be able to pass the glass…

+1, It often forgotten that communication is two way and no point in increasing transmit signal level on say the AP and not on the mobile devices (or CPE for outdoors)
