DynaDish5 P2P 9km link low speed

RouterOS Wireless Networking
1

Hi! I bought two DynaDish 5 and created a 9km P2P link. Channel 5260, A/N/AC, Ceee 20/40/80. TX Power 30 dbm. RSSI -59/-59.
But speed test show me float speed in 3-10 Mbits.
I tryed several modes: 802.11, nstream, nv2. The most better results in nv2.
There is on Mircotik site a one document https://i.mt.lv/routerboard/files/antenas-160404123306.pdf
As I see 9 km is small distance for this device. What do you recomend to improve link speed?

Try and set the channel width to 20Mhz and give it a test like that
