Good receiver, but short antenna cable....
Is incredible to freestyle at 500hz of packet rate at 10mw and never go over -60dbm... I don't fly long range but this SuperD is my favourite rx also for small freestyle rigs. I have it on a 3.5 and i have no problems in find where to fit it.
I am using these receivers also for my r/c semiscale subs, where the dipole antenna of a standard receiver is mounted horizontally in lateral direction and so there are dead points when the boat's bow or stern is pointing into my direction. The diversity receiver eliminates this problem by orienting its two antennas in a 90° angle to each other. I have seen an increased range so far and no more critial boat course related to the transmitter.
Same will apply to planes or drones, where often a single antenna cannot be mounted vertically, too.
Gone through half a dozen of these, very reliable, never had any rx issues even with one antenna.
