I would like to connect this indoor antenna to TP-link 941nd v3, this antenna had 4 mimo with -45 +45 -45 +45 polarization

Its the first one with 4 lines.
I cant find anything about what would happen if I would connect -45 +45 and -45 will there be any use of the third dipole.

What do you think?

it wont increase performance very much...
WiFi TX power is limited to 30 dbm...and all clients must do the same as the router is set to..
Also on those areal's you must use very very short cables
literally directly attached to the router with high quality cables very very short...

well my mistake i meant wi fi is limited to 30dbm max tx rate
in fact as i said you wont get much range boost try with wifi boosters
or something else
nope 1043v2 will not provide bett results all routers are limited
to 30dbm

[tatsuya46]

well 20dbm is over 4x weaker than 30dbm

Checking the countries that support all 13 ch on 2.4ghz at 30db, in fact there are only two countries supporting 36db.
Previously I was setting the Russia which is limited to 20db, that is the factor which was holding me on 20db. One user told me to set Russia, it was mistake.
With Belize, Panama even if I set 30db power in status will shown 24db. Ok its far better than lousy 20db.

Both Belize and Gyana has limited ch on 5ghz I dont need 5ghz at the moment. Panama has biggest ch range on 2.4 and 5 ghz and best TX power. Its best option to use by far. AU is second for 2.4ghz but its bad on 5ghz.

yep diff country domains diff TX power,
Channel 13 is limited and not many clients support it,
as well channel 12....
best to use country domain Canada or Haiti if its still there...and channel 11 is the best one...
The other thing as i said is how capable is your router
and it seems you are limited to 24-25 dbm, it can do that much only...
Better high class routers do 30 max i guess...and dont forget, what you set on the router all clients must support it too...

there is another thing set to short GI, Short preamble..and use HT 20 (54mbit-150Mbit), it has a touch of bett range than 40HT..unless you need a bandwidth

The issue is two fold. TX power is a function of what is hard baked into the wifi chipset firmware/driver on the router and then what country you select.

Regrettably, a lot of older chipsets/routers can't have their firmware updated to reflect the newer allowances of 30dBm (1000mW) and you're stuck with 23-24dBm; or worse/lower. If you use a country that allows 30dBM in settings and set the TX power to 30dBm, but see a value lower on the status>wireless tab of the gui, then that means your wifi firmware has a lower limit hard baked in and there's nothing you can do to change that.

Every 3dB is mathematically half(-)/twice(+) the power; but, this doesn't correlate to range directly changing half/twice the distance (inverse square rule applies here). To double the range you would need 6dBm more of TX power, which is what going from 23-24dBm to 30dBm effectively does (and that works out to 3.98X on the logarithm scale, so nearly 4X the power).
