This is a review of the monitor Skyzone SKY 700D. To test it, I've used the DJI Phantom 1.1 with a Mobius camera attached to a printed 3D Gimbal with a Alexmos controller board, a Rezembi OSD and finally an InmersionRC 600mW video transmitter.
As you can see in the first test with internal receivers and Boscam mushroom antennas, there is a severe incompatibility with my transmitter InmersionRC.
In the second test with an external receiver and onmidirectional stock antennas, you can see good reception up to a kilometer away.
I expect to test the internal receivers with a Boscam transmitter, hopefully with better results

Edited:
Now I'm using a Boscam TS832 transceiver with omnidirectional stock antennas and it works fine, a range of more than a kilometer when not obstacles.
