I take my HF ham stuff all the time camping and on elk hunts. A TrueSdX radio, a small lipo battery, a wire antenna of any type, and a small laptop(11" Chromebook). That gives me full access to voice and data HF. Whole setup without the laptop is maybe a pound? Maybe a touch more? And very compact, all fits inside a mid size go pro case. For VHF/UHF setups and shorter range, it is much easier. Just a handheld radio, and for data would need some sort of data interface like a digirig, and a computer. Of course VHF range is maybe 4-10 miles on a handheld.
