Antenna How many dBI's?


#1

Strangle, i never thought about his matter, but i also did not find anything about it.

  1. How many dBI are each of those antenna’s?
  2. I guess those antenna’s will be 2.4 and 5 ghz both?

ad 2: see the other topic (forum searches FTW!).

Strange, i have read that topic earlier, but somehow i did not manage to remember what indeed was written there.

I’m getting old and my memories are abandoning me.

Thanks for the reply. Now only one question remains…amount of dBI.


#4

that’s indeed one question i forgot to ask, i asked again via e-mail, stay tuned :wink:

The gain of the antennas is 3 dBi @ 2.4 GHz and 5 dBi @ 5 GHz. One of them is dedicated for the 5 GHz band (3×3 MIMO ac card), remaining two are shared between both of the cards.

@sairon, It was still not clear to me how many antenna’s the Turria Omnia would be having, but according to your reply, it will be 3.

1 - Dedicated for the 5 GHz band
remaining two are shared between both of the cards.

My question about the amount of dBi is answered,

A new question is risen and that is, will it be explained somewhere which antenna’s are shared and which is the dedicated?

Because i am planning to replace them with other antenna’s.

Yes, there are three antennas. Dedicated is the middle one, the remaining two are connected to the WiFi cards using a special circuit which mixes the 2.4 and 5 GHz signals together. There are also two extra holes for SMA/RP-SMA jacks if you ever need them (for example to connect LTE antennas).


#8

@sairon, the two extra holes you used in the example for LTE, so they cannot be used as extra antenna’s for wifi?

Hi.,…in my case I didn’t expect the 2 dBi showing more background noise, though. I expected a lot more noise on the 5 dBi. But like I mentioned earlier, it could just be that the 5 dBi picks up the source of the background noise more clearly so they look like peaks instead. Also, the 2 dBi picked up more noise near 2.5 ghz.
