Just a mega-quick post about my experiences with the 4Hawks antennae on my M2Z, in case anyone is considering a purchase and can’t decide which to buy, (Other Antennae are available ).
I have both the SR and the XR
I mainly bought these to maintain a clear video signal.
SR - Pretty much the same as the stock antenna WITH parabolic reflectors - video is a little more stable but not worth the effort, (IMHO) - the ROI is too small
XR - Oh so much better (50-100% increase in challenging environments over stock) - however it does make the controller M A S S I V E
