Altrum N200-EXT 5GHz diversity combiner

Dear Sir,

I should like to offer for our customer a radiolink over sea, distance 6km in band 5,4 GHz and 5,8GHz.
For me it seems reasonable to use your Altrum N200-EXT with a disc antenna.
Can you advice is this reasonable and especially have you for this some kind of diversity combiner to solve the problems of interference with reflected from water wave. Please advice the best solution. The solution is needed for the pilot application what will follow for a series for wind parks.
