can anyone tell me where I can order stock antennas for my P4 controller? I tried chatting with DJI and kept getting shuffled around to different departments,  and I'd rather not go with after market antennas I'd rather kept everything stock, can anyone help???

If you want to replace the antennas, it's recommended to send it in, and our engineers will help you do that.
Since we do not provide warranty if problems caused by improper installed.
