The HobbyKing ™ retractable antenna system is designed for FPV use. This allows the Antenna to be mounted far away from sources of obstruction and RF noise. On smaller MultiRotors proper separation is hard to do with size constraints, now with the flip of a switch the antenna can be deployed for an unobstructed Locked In FPV experience.
The retraction allows for takeoff and landing without the need of unsightly tall landing skids as well as easy transportation. The boom can be cut to any length and comes with the proper Antenna to TX extension and mount. For activation you will just need one extra channel on you tx to operate the retract unit as it comes complete with the actuation unit and motor.
• Allows for an unobstructed FPV Antenna without sacrificing portability and size
• Comes with extension cable
• Adjustable length
• CNC Alu retraction unit.
Boom: 4mm carbon 300mm (cut to length)
Extension: 510mm (SMA)
Does what it's designed to do, it's just a bit bigger than i thought it would be - it is 90mm long, so only really usable on bigger craft. I ordered it for my 350 size quad, but it was too big to fit the space available. I would like to see a smaller version.Ottimo prodotto malgrado il cavo dell'antenna sia una prolunga RP-SMA e non SMA come cita la descrizione!!! Il peso del sistema retrattile compreso la prolunga e il sostegno senza antenna "54gr" e non 33gr.
