941v5 change ubnt+ dual-polarization antenna signal difference???

ahkxhyl

1.Rub the net 941V5 to UBNT+ dual-polarization antenna signal is very poor, the search for wireless signals is only a few -60 more, most of them are in -80 more ~ -90 more, the speed on the link is only 200 ~ 400k less than 2m speed ~ ~ and I use a dual-polarized antenna + 8187 network card and then use a network cable to connect the computer The network speed is more than 10m ~ 20m ~ ~ What is going on with this???
2.The WiFi speed of the Pandora relay with K2 is more than 7m~9m??? (Connect the LAN port of K2 with a network cable, and connect to the computer at a speed of 20m-30m)
3.The place where I live is surrounded by high-rise buildings (urban villages) There is a lot of wifi in the community~~~
4.The dual-polarized antenna is placed outside the window, and the ~~ 941v5 is placed vertically in the house
Seek advice~~~~

The problem has been solved
My approach is: change a Shuangling, a cannon antenna connected to a 941v5 network cable, plug in the computer, and the network speed is more than 20m. Even the K2 network cable is about 2.5 The network speed hovers above 10m Occasionally 6-7m turns off 2.4g and turns on 5g ubnt reduces the power I think is the impact of the 941 signal Need to lengthen the network cable? I don't know if the dual-polarized antenna is an antenna problem or something else, and I can't adjust a lot of positions? The network speed of connecting the dual-polarized antenna is only a few k, I found a seller who sells dual-polarized antennas on Salted Fish, and people do not admit the antenna problem

This flat plate dual polarization is really a bit unreliable, and the signal is very high, but the bit error rate is particularly large

Your Shuangling antenna is homemade or bought, introduce it and take a look, I am also worried about this tablet

Shuangling bought the interface is not strong The interface line fell off during the week I wrapped it by hand and then pasted it with adhesive tape I don't know how to solder things and there are no tools Shuangling bought a very poor signal I changed it myself~~

Dual-polarized antenna I also want to buy one to play with
