Improvise, adapt and overcome. I think I could make a reconfigurable antenna but the ideas I'm coming up with are very crude. It's not that it would be inefficient but it would be complex. Electronic and Pneumatic logic separate from the feed line.

I think I just witnessed Electromagnetism interference completely disrupt a cellular signal. I don't think I've seen lightning do that before. I think the plasma can cause this type of disruption. I'm not familiar with the exact Physics of plasma but I seem to recall being able to hear thunderstorms on some type of radio.

Waves are really cool.
