[4] The team plays its home matches at the multipurpose stadium "Arena Radunia", which was put into use in 2017, with a capacity of 450 seats.

[8] Radunia's climb in the late 2010s and early 2020s, as well as its ability to regularly bring in players with top-flight and second division experience, was owed to support from the Stężyca county and its mayor Tomasz Brzoskowski.

[9] Heavy spending related to Radunia was cited as one of the main reasons for the county's dire financial situation at the start of 2024, with over 100 million PLN of debt to Stężyca's name.

[10] Following the 2024 Polish local elections, the new mayor, and former employee of Radunia, Ireneusz Stencel withdrew all of the funding from the club, resulting in departures of most of the players and staff.
