I put my Yaesu FTM-100D into a Pelican case as a bug-out option. It'll run from a wall outlet, 12V socket or the LiFePo battery. Not really something I'd want to walk around with, but it'll run from the car seat or park bench easily enough.
Thanks for the tip on the HF antenna... I'll pass that along.
Looked like they were using a T-shape antenna for one of the rigs, strung up between two trees.
The other rig was using the 1/2-wave antenna on top of the building.
