Hi, I just modded my controller with the Argtek range extender antennae and I've run into problems. There seems to be very little signal coming from the controller and my video feed and range are greatly reduced. I've gone back into the controller and checked connections, swopped around wiring and antennae but nothing has worked. I bought the mod from amazon.com and I'm pretty confident that it's a genuine blue proton product. I believe that the long antenna included in the mod are 10 dbi which from what I've read should be powerful enough to do the job, it's almost like there's very little signal being transferred in and out of the controller. Could anybody suggest a test that can be done to assess the signals going to and from the controller? To compound things, I managed to damage the original antenna taking it out so I can't even revert to my original setup. I have been trying to source a replacement P3 antenna, from what I understand any P3 antenna will do? I have found it very difficult to source replacement parts for the P3 SE, maybe in other parts of the world it's easier but in ireland the dji store won't ship to here and there are very few replacement parts available on ebay etc. I have been in contact with dji support but that means shipping the controller to the Netherlands for repair when all I need is a replacement antenna which I can install myself. I'm fairly new to this so any info or advice would be much appreciated. Many thanks
