I've seen OTA failure, internet failure, and cable failure. Make sure your choice of transmission is backed up. Mother Nature is going to take us on a wild ride for the next few years at the least.I heard on KNX this morning that the plan is to maintain a containment line at the area of the transmitters, so the fire won't get there. The Observatory will also be protected. Those communication towers (there is more than just TV transmitters) would be bad news for emergency services and communication in general if they were destroyed. In the case of cable subscribers (and possibly satellite), they are likely not dependent on the towers for their tv reception. Those of us with antennas, however, would see what we thought of as the most reliable way to receive tv transmissions turned into the least reliable.
