Typically helical antennas, which are essentially a circular polarised patch antenna, are used for long distance work. I doubt you'll be doing much long distance work with the quad! However if you are, you could use both a helical and skew planar antenna on a diversity equipped ground station. These pick the better signal of the two for the video feed. For typical quad applications though, you shouldn't need to use the additional unidirectional range that you can get from a helical antenna and a skew planar will be a better option.
