As the weather turned cooler, I suddenly had an idea: you could try renaming "Wandering Radio" to "Wandering Ham Radio Equipment".
(In fact, it could also be done through a formal rental arrangement.)
To illustrate this point, for example, I might not bother renting equipment like power supplies and antennas.
However, because I only use my portable power station a few times each year, I don't want to keep a large battery (like DJI's 1-hour power station) at home, and I spend about 360 days of the year sleeping at home.
If you have access to a high-power, large-capacity power supply (like those used with portable generators), I would be very interested in renting one from you.
* If some HAMs have a fixed antenna, they may need to rent a portable antenna for events like field days.
If you could also provide rental options for folding tables, folding chairs, and folding umbrellas from 野架, that would be even better.
