应该没事，装上天线试试，能用就是真的没事

The handheld radio transmitted for 0.5 seconds without an antenna, and I tested it by transmitting to a repeater; it seems to have worked. Is it possible that the repeater is still functioning?

It's okay.

It should be fine; just install the antenna and see if it works. If it works, then there's really nothing wrong.
