Dear All,
Honestly request the idea about RB position with the following questions:
1.What the ideal distance between AP with WDS on the tower.
2.Wicth one more suitable to set as AP or WDS between 2 ea RB ( RB 411,RB 433)

Best Regards

...and then 15db omni to AP(RB411) and 24db grid to client(RB433).
The 433 is a more feature/option rich RB, perhaps you may consider using at for the AP instead.

Thank for your support,I will follow as above mentioned and will keep track what I doing and what the result will be to share later on

All,
I have purchased Mikrotik RB411 and RB433,I plan RB411 as AP and RB 433 to share.Additional I have Hyperlink OMNI 15 dbi and the other Grid Sectoral 24 dbi.Honestly requested advise how to the best design relate to an Antenna I have.
