Hello, I recently just bought an H920+ with CGO4 gimbal. I've been involved with RC over 30 years and started a drone business in 2014 that is doing quite well. This model has always intrigued me since it's inception but the early release price tag of it was overinflated IMO. I own or have owned nearly every prosumer and industrial UAS platform on the market (multirotor as well as fixed wing) from the Mavic Mini through the Matrice 600 and S1000. I finally pulled the trigger on this H920 when I found a seller liquidated them on eBay for around $2500. I managed my expectations since I was aware the tech is 3+ years dated at this point and I've had a few Yuneec models with the integrated Android tablet remotes which produce a mediocre laggy low res FPV live view with limited range but I had high hopes since the CGO4 is pretty much a Panasonic GH4 which is a great camera. Now the aircraft actually flies quite well and as I assumed, the cam is excellent...my gripe however is the RC control range. I replaced the 5.8 antenna with a Fat Shark patch antenna which made a world of difference on my video stream...much cleaner and plenty of range. What's killing me are the 2 2.4 antennas. I'm assuming 1 is for transmission of the RC control to the drone which drops out around 1500ft and the other is another 2.4 receiving antenna providing telemetry data to the ST16 which drops out even sooner than 1500ft. Has anyone tested any different antennas besides the overpriced 4 Hawks or Itelite? Has anyone modded the receiver's antennas on the drone as well? I really want to keep this platform in my fleet because I love the results of the CGO4 camera but I just can't work with only 1000-1500ft of range. PLEASE HELP! ANYBODY!
