It's time. No matter if everybody is happy about that or not, Digital FPV is taking over the FPV world. The DJI Digital FPV System is with us for more than a year now, and it seems like the competition does not have anything to compete with yet. Fat Shark Byte Frost was an abysmal fiasco, and Shark Byte is only scheduled to go public.
Caddx Vista with DJI camera
The original DJI Air Unit offers the best range, image quality and functionalities. However, there is a price to pay: it's rather big and heavy. Caddx Vista solves that problem: it's smaller and lighter and should fit most FPV frames. Even small toothpicks. In return, you lose the second antenna and ability to record DVR footage in the drone. There is no Sd card slot!
Caddx Nebula Pro Kit
The alternative to a full-size DJI Air Unit is Caddx Nebula Pro camera with a Caddx Vista Kit. Although the radio module is the same size as full Vista, the camera is smaller and lighter. And yes, the video quality is as good or maybe even better than with the original DJI camera. Kudos to Caddx!
iFlight Crystal HD
The iFlight Crystal HD is another idea of adding a good-looking directional patch antenna to the DJI FPV goggles. Instead of antennas that you have to mount with a double-sided tape like Lumenier AXII HD, why not to put antennas inside the goggles front plate? Looks much more professional than anything else and works the same way!
Lumenier AXII HD patch antennas
The original LHCP antennas shipped with DJI FPV goggles are, well, not the best things ever. The Lumenier AXII HD set consists of 2 patch, directional, and two omnidirectional LHCP antennas. Gain? Substantial when you are flying in front of yourself. Price to pay? Weaker signal reception when flying behind you. Is it worth it? Tests say that yes.
