In principle, the radiotap header length is variable, but in practice, it is virtually always 64 bytes; this is an accomodation for libpcap/tcpdump, which historically could not handle variable-length headers.

Not in all cases (not for Token Ring headers with routing information, and not for 802.11 headers with four addresses, for example), but it *does* support variable-length radiotap headers in the 0.9.x release.
