This antenna has a real good performance and brings a Zimmerantene a hard to beat reception quality. Since the antenna has a very high directivity, you should inquire in advance from which directions transmitters are to be expected. Should stations be expected from entirely opposite directions, there can be problems when you change channels, which would eliminate only by 'turning'. Perhaps then a Runddipol or a rod antenna would be better. But in my case all come emfangbaren programs from one direction, the antenna plays its full performance.
