can this configuration work?

I have just bought a Mikrotik RB 133c with 600MW Card to transmit on 5.8GHz to another Mikrotik RB 532 base station with another 600MW Card on a point to point connection.

The distance is 11KM and the antenna I bought are 30dBi 5.8Ghz Grid antenna for both end.

My friend are saying that the power is too much, that it may affect the radios. Can I return the equipment?

Thanks.
