Here is a 10.5 dBi half sphere helix 2.4GHz LHCP and a proprietary FPVLR 9.3DBI parasitic disk helix 5.8ghz LHCP to give you very wide beam width and ease of aiming, yet some very usable directional gain to increase both your video and rc and telemetry about 3x vs stock antennas.
This kit contains 1 u.fl to rp-sma female cable (rg-178 coax) 9cm long (for 2.4ghz rc control antenna) 1 u.fl to rp-sma female cable (rg-178) 20 cm long for 5.8GHz wi-fi antenna (video) 1 2.4GHz Half Sphere helix 9dBi LHCP (to extend rc range) 1 5.8GHz LHCP 4.25 turns 5.8ghz helix antenna (to extend wi-fi/video range)
This kit has a slightly larger 5.8GHz LHCP antenna to match the CG03+ antenna polarization, total gain is 11dBi. It
This is an additional Half Sphere Helix antenna used to upgrade to a H-Pro type of setup. 10.5dBi of gain,
