8/6/2022 update : You need to file down the protruding ears of the center part a bit to avoid from rubbing with the frame Antenna replacement for internal ExpressLRS module of the Jumper T Pro. I was bothered with the stock antenna which took too much space for what it's intended for. I used a Happymodel EP1 antenna (longer one) to replace the original Airgain antenna and Improved the signal quite a bit (see picture for rssi dbm comparison with stock antenna). Any 2.4 GHz antenna with a ufl connector will do. You can also make your own using these guides; https://www.youtube.com/watch?v=C9a169YysyA&t=536s https://www.youtube.com/watch?v=U8__pLUnfwA The antenna can be tilted up and down and can also be rotated 90 degrees. The antenna does not get in the way even when in the down position. Printed mine in resin except the shoulder part which needs to be printed in PLA to avoid it from breaking when screwing in the retaining screw. The tolerances are tight so you may need to rotate it a few times or sand it down to make the motion smooth. Snake the ufl end of the antenna from the top of the center piece out to either side and do the same for the shoulder part. I used some CA glue to bond the two halves of the antenna together. Disassembly tip; You need to remove the 4 pcb screws and lift the pcb to release the ufl antenna because the connector for the pot switch is in the way. All credit goes to drooboid for the original design.
