If you are using a linear whip antenna on your micro quad and using a circular antenna to receive you would be experiencing a 3db loss due to the mixed polarisation signals, for each 3db drop in signal that is a half in power so effectively your 25mW vtx will only be seen as transmitting 12.5mW.
A biquad? The biquad is the linear equivalent to the crosshair, with its clean radiation pattern and great efficiency. We of course added our own twist to it by stretching its bandwidth to cover the whole 5GHz ISM band. This make it usable with both digital and analog systems. Mount it right on your goggles whether they have top or side SMA connection, the included low-loss semi-flexible extension have them covered.
