Not sure but I think service manual says something about valve core/stem as signal sender. Both are aluminum to avoid dissimilar metal corrosion/failure??
Yes, the stem with cap is the antenna. Do not paint or cover it up in any way. Also, I understand there are TWO different 'systems' in our crossfires (frequency). Make sure the stems match the frequency of the receiver before you buy them. I also heard (have not confirmed, as mine are bypassed forever) that some of the replacements are able to be used with either receiver (dual transmit frequencies, selectable after install). Good luck!
