RouterOS Wireless Networking

Hi,
I Have a RB433AH Access Point with 3 flat Antenna.
the wireless card are dbii 5GHz-A and works on 10MHz Channel Width.
they works for 6 month without any problem till now the users have a poor wireless connectivity.
I set my cards to work on just one channel!!!
when I scan for My AP, it shows like this:

This happen when scan with any device like UBNt and mikroitk and other brands.

In the frequency scan you have signals of -17 which too high and is probally overloading the radio card, i would suggest you use RF screening on the antenna’s and may have to move the antennas further apart,

How many radio cards are attached to the RB-433AH?

Thanks a lot.
I have 3 Dbii card on my radio.

I only use 1 radio card per routerboard with RF screening and have no issues but using several radio cards into one routerboard will cause self interference and especially as the bandwidth usage increases?
