ANY SIDE EFFECT/COMPLICATION USING 5GHZ-TURBO BAND?

Pls is there any side effect or complication using 5ghz-turbo on my mikrotik radio.
I want to cover 11km with RB600A as the AP and RB433AH as the client and R52H in each one of the radio

Signal strength usually drops by about 3dB.

Slightly more prone to interference.
