I really need to put up a "No I can't have solar panels I do ham radio" sign since it's that time of year again

Or just do what someone here said and put up a "No Solicitation but have some water" sign with a cooler

@farewell_ladmin oh. RF coupling. Yeah that could be a problem. Never thought of that.
@xabean I usually just tell them that having big old sheets of metal on the roof would make things "bounce" but yeah the RFI would be nightmarish too
