Someone else mentioned that this could be a good opportunity for misinformation. That is a great idea while we search for a long-term solution. We could put up a small plane full of transmitters fed by computers with each transmitter sending what might look to the enemy like a drone feed. Real feeds might be on some channels but garbage feeds would be everywhere which would waste the enemy's time and resources trying to sort out the junk feeds from real ones. A secure channel would be used to tell authorized persons where the real feeds were. The challenge would be to make the fake feeds have the same electronic characteristics as well as the same appearance as genuine feeds.
