Note:
The Raptor Antenna’s incorporates a stronger SMA to Coax production method which includes a crimp metal collar.
On our first production batch from December 2016 we received feedback from some customers that they were experiencing breakage of the Raptor at the SMA to Coax junction in a crash.
We worked on a stronger fixing method where we have carried out testing to compare the fixing methods of the SMA to coax cable for strength and then passed it to test pilots to further evaluate the new method. The new method proved to be much stronger.
What we have concluded is that any antenna mounted on a top plate will not last and it will only be a finite number of crashes before the inevitable. The recommended mounting method is to mount the antenna out the rear of the drone and fasten the coax to the plate with cable zip ties or similar restraint. Whilst this will help nothing in this hobby is indestructible.
All production from January 2017 onwards has incorporated the stronger method.
