The name "Penna Wireless" is an often-used abbreviation of "Pennsylvania Wireless". In 1920, Penna Wireless distributes Radisco parts. In 1925 they offer a "Selectedyne" receiver.

The history of Pennsylvania Wireless is largely unknown. In an advertisement they state an incoporation date of 1910.

The address Florence Ave seems to have been their company seat throughout their existence (November 1924, The Radio Trade Directory, under the heading manufacturers of Vacuum Tube Sets on page 82, and also the August 1926 edition of the McGraw-Hill Radio Trade Directory).
