Yes, a dual band mimo type patch would be good -- as you could feed the control TX channel into one of the 5GHz elements, and use 2 2.4G elements for the wifi channel, just keep the whole thing pointed at the P2V....
For 2.4G these look ok, 120x120mm 9dBi so not too big for a single antenna, or use a pair.. quite cheap if you poke around...
