iv no idea if this will get the longer range, id rather go for 22DBI highly direction dish types but something like this panel with intigrated wireless to save on the cable loss perhaps...

Don't forget your licence

the 5Ghz doesnt need a licence, you can get long range with unlicenced open kit too, with the right directional high gain arials over line of sight for point to point and point to multipoint setups....
oc your going to get a lot better coverage with 2.4Ghz 11N if you use highly directional line of site, assuming if you dont have a lot of 2.4Ghz between sites...
the spec of that Motorola PtP 400 lite Bridge Kit Includes:
2 x Motorola PtP 400 lite Units
2 x Mounting Brackets
Price: £3,456.00 (£3,974.40 inc. V.A.T.) kit is a little OTT today for
22Mbps it seems, you could get a microwave 1gigE radio for that...
