Does it perform well enough to replace my patch antenna? Yes it does but remember it's a directional antenna. The more turns, the longer range you get but your beam gets narrower. The one your showing is 5 turns. Mine is 3 turns which is more suitable for what I need it for. I wouldn't go no bigger then 5 turns my self. Unless your flying a plane so more turns the better.
I'm not sure what your using for a Omni antenna but that hybrid triple feed directional is about the same as my True rc directional. I'm going to try a different omni antenna. VAS SkyHammer 5.8GHz SMA Receiver Antenna - RHCP or LHCP this has a little more gain then the one I'm using now.
