The ARRL every year holds a competition we call “Field Day”, which is an exercise in readiness for emergency communications. I used to be a member of K2AA in New Jersey, and we regularly took first place in our class on Field Day.

You get extra points for running your radio equipment on emergency power, which helps encourage operators to invest in that sort of gear. So, there are a lot of hams out there who will definitely be able to run repeaters and transceivers in the aftermath of disasters.

K2AA owns several military surplus 50’ antenna towers (I think the AB-577 model?) that we can have up and running in a very short period of time. They break down into a bundle that fits in a pickup truck, about 8’ long, weighing about 300 lbs. They will hold some big honking antennas. We would choose a remote site show up the day before with RVs and tents and generators and computers and set up for the weekend.
