Stealth and RF
Seems to me an easy way around the "if you aren't radio silent the enemy can triangulate your position without radar" problem is to communicate with a satellite. Use beam steering to send messages UP.
Unless something is above you (maybe a network of enemy weather balloons?) they won't be able to receive your transmission and you remain stealthy. It won't work with enemies who have their own satellite network, but foes at that level have much better radars able to see the small radar cross section the F35 presents anyway.
