Help with signal to noise ratrio

I am new to mikrotik and i would highly appreciate some help. I have several clients at different locations having good Tx signal strengths but poor signal strength and having a look at the signal to noise level i can see the ratio to be below 10db. I now the noise levels are affecting my signal strength but i need some advice on how to go about it. Any suggestion is welcomed.

which frequency you use for broadcasting. try change your operating frequency…

Iam using the 5200GHz on one sector and 5260GHz on the other sector which are facing two different directions. i have also tried changing the frequencies on bgoth sectors but no improvement so far
