3DNater is right about using an OEM antenna. However, I believe with Taranis radios, you void the warranties once you start soldering. If you haven't already started, I would suggest sending it back to the factory. My friend did that when his JR 9503 had a broken gimbal and they fixed it up for a very low price!
Good Luck!
