The FPV Googles are REDPAWZ EV800 https://amzn.to/2qpX4QB Redpawz googles are good; however, there are udated googles called EACHINE EV800D FPV for about 30 dollars more, and they may be better. https://amzn.to/2qpkNAt Realacc Omni Antenna from Banggood.com http://shrsl.com/vwdq This Realacc 5.8G 5dBi 50W Omnidirectional Flat Panel Antenna is a Omni Tower Plated FPV Antenna SMA/RP-SMA I believe it works well. However in this video, I don't see much difference; however, I do like it and think it works. I believe the signal is better than stock antenna.
