@lopta @jpoesen I've packed up a roll-up J-pole antenna in the past, stuck it into a saddle bag, then unrolled it and hung it from a hook on a nearby tree when operating. No ground plane needed. At least plausibly this works too if you have a suitable flagpole mount (fiberglass mast with a hook at the top).Or build the J-pole right into the flagpole, https://www.worldradiohistory.com/Archive-DX/73-magazine/73-magazine-1982/73-magazine-09-september-1982.pdf has a design from Jim #W5AOX in 73 magazine from 1982.
