I regularly drive through a tunnel under the Thames (The Blackwall Tunnel)
durring which the radio on FM turns to static as I would expect. This tunnel
has several bends of 20 to 30 degrees where the radio signal returns. I would
assume this is the effect of some sort of amplification of the signal at these
points. Could this be used in arial or antenna design?
