Hi It’s a pretty good bet that what ever is *really* is a generic PNP or NPN device will drop in. You need a low frequency device like the 3904 series. It’s going to carry about 40 ma to your antenna. A high(er) current part (Ic max > 100 ma) is better than a low(er) current (Ic max < 20 ma) part in this case.
