Well you do need a portable repeater on a different frequency, just in case the oher goes down....telescoping pole with maybe a comet gmrs basr antenna. A scanner to to listen to public safety, and a high power mobile for simplex operation, covering all bands or a stack of radios covering both ham and commercial. You can tell i like radios.
What lessons did we learn from the movie lone survivor? Having good comms can make a difference.
