Don't know, but it's an RF transformer. Never had one to take apart. Specs and Philco info do not say anything either. Don't know if there was any impedance transformation either. A dipole has a nominal impedance of 75 ohms. Don't know what that twisted-pair lead-in wire was. The transformer could have been 1:1, but I suspect the nominal radio balanced input impedance is probably higher. Won't be critical for reception anyway.

Did you get the two jpegs I emailed you from work? Didn't see a reply from you about them. Lemme know...
