Summary

Did not print or test right now, just an idea to mount the TBS immortal antenne verticaly on the Alien 5" or some frame with 35mm high standoff.
Did ad an aditional solution for vertical mount the Immortal Antenna. Lip slides over the top and bottom plates to prevent slipping, holes for the antenna become closer to the end to give the antenna a tighter fit.
As usual, feedback is aprichiated.
Best printed with TPU
Design looks a bit awkward but ist on purpose to be printed with as less support as possible.
If you print and test please give feedback so i can improve, thanks
