The one I have here is the latter, Graham, with the SO239 connected to the telescopic antenna socket via the components you mention. That circuit diagram matches exactly the one in the operator's manual I have here.

Just for the record, and I know I shouldn't really be doing this; If I retract the telescopic antenna section by section, the TX LED power indicator increases.

I only did this test very quickly and only retracted a couple of sections so as to avoid blowing the output Transistor.
